The site consists of approximately 96 acres owned by the City of Peabody and approximately 119 acres owned by Eastman Gelatine Corporation and leased to the City. The site includes approximately 47 acres of wetlands, 74 acres of mixed upland hardwoods woodland, and 94 acres of upland meadow vegetation. The proposed 18-hole golf course will be of a returning nine design with a par of 71. Course length will be approximately 6,690 yards from the back tees. Portions of the course will be constructed within the resource areas of"bank" and "bordering vegetated wetland" and within the 100-foot buffer zone. In designing the proposed course every effort has been made to minimize the potential of environmental impact. The basic design is a links-style course, incorporating native grasses and topographic land forms to establish both course identity and the separation of holes. Avoidance of wetlands has been a primary focus of the design efforts. As a result, no ' filling or loss of wetland area will occur. Construction activities will be conducted in strict conformance with a comprehensive soil erosion and sediment control plan. All future course maintenance activities will be guided by a turf management plan ' incorporating the use of state-of-the-art integrated pest management. Irrigation water for the maintenance of the golf course will be obtained from existing ' groundwater wells owned and operated by Eastman Gelatine Corporation. This water will be conveyed via Eastman Gelatine Corporation's supply system to Sidneys Pond, from which the water will be pumped through the irrigation system. 2.0 Wetland Resource Areas ' Wetland resource areas on the site, as defined by the Massachusetts Wetlands Regulations, include bank, land under a water body or waterway (LUWBW), ' bordering vegetated wetland (BVW), isolated land subject to flooding (ILSF), and riverfront area. The extent and boundaries of these resource areas were flagged by EMC Environmental Services in November 1997. The flag locations were surveyed f1 by John J. Decoulos and depicted on a plan entitled"Plan for Determination of Applicability Proposed Peabody Golf Course Existing Conditions" and dated December 31, 1997. The Peabody Conservation Commission verified the accuracy ' of resource area boundaries located within the City of Peabody through the issuance of a positive Determination of Applicability on February 17, 1998. All resource area boundaries, as flagged by EMC Environmental Services, are depicted on Figures 2 , through 4. Brief descriptions of each resource area follow. Bank ' Banks on the project site include those confining intermittent stream channels, the ' banks of Sidneys Pond and Meadow Pond, and the bank confining Strongwater Brook, a perennial stream located at the southeastern corner of the site. Stream banks on the site generally are 0.5 to one foot in height and are composed of ' unvegetated mineral soil. The stream bank below Meadow Pond in Peabody is approximately one foot in height and is composed of organic soil. All banks on the site appear to be significant to the interests of storm damage prevention, prevention ' of pollution, and protection of wildlife habitat. Land Under a Water Body or Waterway (LUWBW) , LUWBW consists of the bottom of the stream channels and ponds on the site. Within stream channels, this resource area generally is one to two feet wide and is composed of stony glacial till. The LUWBW of Meadow Pond and the stream immediately below it is composed of muck and the LUWBW of Sidneys Pond is composed of sandy gravel. The LUWBW of intermittent streams appears to be , significant to the interests of protection of ground water supply, storm damage prevention, and prevention of pollution. The LUWBW of Strongwater Brook, Sidneys Pond, and Meadow Pond may also be significant to the interest of protection ' of fisheries. Bordering Vegetated Wetland(BVW) , BVWs occupy a total of approximately 44 acres in nine locations on the site and ' include two basic types: wet meadow and wooded swamp. The dominant wetland vegetation species within the wet meadows include Common reed-grass (Phragmites australis), Purple loosestrife (Lythrum salicaria) and Reed canarygrass (Phalaris arundinacea). The dominant wetland vegetation species within the wooded swamp areas include Red maple (Acer rubrum) in the overstory; Spicebush (Lindera benzoin) in the understory; and Skunk cabbage (Symplocarpus foetidus) on the , ground. The vegetational community of each BVW is indicated in Table 1. 2 ' r Table 1. Vegetational Communities -Bordering Vegetated Wetlands. ' Wetland Area Vegetational Community B wooded swamp rE wooded swamp rF wooded swamp H wooded swamp I wet meadow ' J wooded swamp rK wooded swamp/wet meadow L wooded swamp/wet meadow rV wooded swamp The BVWs appear to be significant to the interests of ground water supply, storm damage prevention, prevention of pollution, and wildlife habitat. ' Isolated Land Subject to Flooding(ILSF) rNine areas of the site, totaling approximately three acres, are ILSF. As with the BVWs, the areas of ILSF include both wooded swamp and wet meadow vegetational communities. The vegetational community of each ILSF is indicated in Table 2. Table 2.

Vegetational Communities - Isolated Land Subject to Flooding (cont.). Wetland Area Vegetational Community , N wet meadow , P wooded swamp Q wet meadow ' R wet meadow T wooded swamp U wet meadow ' The ILSFs are significant to the interests of ground water supply, storm damage prevention, and prevention of pollution. ' Riverfront Area The riverfront area associated with Strongwater Brook exists in the southeastern corner of the site. This resource area extends for a distance of 200 feet from the west bank of the brook and is located entirely within the Town of Salem. This area ' consists of the densely-wooded, northeastern slope of the hill containing the Cedar Grove Reservoir. 3.0 Effects of the Project on Resource Areas In designing the proposed golf course the golf course architect adopted a three-tiered , sequential approach to wetland protection and impact mitigation. Under this approach the first focus of the design was to avoid wetland areas: only where ' avoidance was found to be impractical does the proposed design require direct alterations to wetlands. The second focus of the three-tiered approach was to minimize the extent of the direct alterations where avoidance was found to be impractical. The third step of the approach, a step which was implemented only after efforts consistent with the first two steps were exhausted, was to define a mitigation , program to offset the loss of important wetland functions resulting from the alterations. As a result of adopting the three-tiered design approach direct alterations to wetlands ' have been limited to the hand removal of tree canopy and trimming of shrub layer 4 ' ' vegetation to permit line-of-sight and play-over of specific segments of wooded ' swamp and the installation of pile-supported boardwalks to provide for the crossing of wetland areas by golfers and carts. The following are detailed descriptions of each of these alterations. ' Tree Canopy Removal and Shrub Trimming The removal of existing tree canopy and the trimming of shrub layer vegetation is necessary at the fairways of holes 2, 5, 6, 7, 14, and 15 to allow for the creation of line-of-sight and play-over of wooded swamp wetlands. The clearing necessary at ' holes 2, 5, and 6 will occur in ILSF only and will result in the removal of a total of approximately 8,130 square feet of canopy vegetation. The clearing necessary at holes 7, 14, and 15 will occur within BVW and will result in the removal of a total of ' approximately 4,230 square feet of canopy vegetation. All such vegetation removal and trimming will be conducted using hand tools only (e.g., chainsaws). No mechanical equipment other than chainsaws will be used in the wetlands as part of ' this work. Trees will be cut at the base and all branches and trunk sections will be removed by hand or by lift staged on adjacent upland areas. Vegetation will neither be pushed nor dragged from the wetland areas. Shrub layer vegetation will be trimmed to a height no greater than that necessary to accommodate line-of-sight and play-over. To ensure that only that level of trimming required to achieve this standard is done, shrub layer trimming will not be conducted until final grades have been established on either side of the wetland crossing. At a minimum, shrub vegetation will be retained at a height of two feet or greater. ' The removal of tree canopy and trimming of shrub layer vegetation conducted as described above will not destroy the wooded swamp areas of the site. These areas ' will continue to function as viable ILSFs and BVWs. Neither the soils nor the microtopography will be altered and existing hydrology will be retained. The wooded swamp areas so altered by this activity will continue to advance the interests ' of ground water protection, storm damage prevention, prevention of pollution, and protection of wildlife habitat. However, the removal of trees will result in a loss of tree canopy habitat, thereby reducing the capacity of the affected areas to support ' wildlife species dependent upon this vegetative strata. This activity is consistent with the General Performance Standards specified at 310 CMR 10.55(4) in that it will not result in the loss or impairment of more than 5,000 square feet of BVW. ' This activity also is consistent with the General Performance Standards specified at 310 CMR 10.57(4)(b) in that it will not result in the filling of ILSF, an alteration to the permeability/transmissivity of the soil substrate, an alteration to the pollution ' prevention capacity of the soils, an alteration to certified vernal pool habitat, or an alteration to rare wildlife species habitat. F,` Installation of Boardwalks , Golf cart/walking paths will cross wetland areas at five locations: from the 6h green , to the 7h tee (approximately 40 feet in length), from the 7th green to the 8th tee (approximately 310 feet in length), from the 12th green to the 13th tee (approximately m 15 feet in length),from the 15th green to the 16 tee (approximately 50 feet in S � S � ( PP Y , length), and from the 17 green to the 18 tee (approximately 20 feet in length). The crossing from the 7th green to the 8th tee is through a wet meadow: all other crossings S are through wooded swamps. The wetland resource areas over, or through, which the boardwalks will pass include bank, BVW, and LUWBW. Boardwalks will be ten - feet in width and will be constructed of pressure-treated timber as depicted in Figures , 16 through 20. All boardwalk crossings will be constructed by hand. No mechanical equipment other than hand-carried soil augers will be employed in the wetlands to conduct this activity. All soil displaced by the pile supports will be hand removed ' from the wetlands so as to retain the existing microtopography. The construction of boardwalk crossings will have virtually no effect on the soils, microtopography, or vegetation of the wetland resource areas of the site. The boardwalk from the 7th green to the 8th tee will be elevated a minimum of four feet so as to permit the unrestricted passage of sunlight to the meadow vegetation located beneath it. The ' boardwalks through the wooded swamps will be sited during construction so as to avoid the loss of trees. Accordingly, this work is consistent with the General Performance Standards specified at 310 CMR 10.54(4), 10.55(4), and 10.56(4). , 4.0 Activities Proposed Within the 100-foot Buffer Zone ' Activities proposed to occur within the 100-foot buffer zone to BVW and bank resource areas include the construction of golf turf surfaces, cartpaths, surface water , drainage facilities, a portion of the clubhouse and clubhouse parking lot, the irrigation pumping station, and long-term golf course maintenance activities. The locations of all physical structures to be constructed within the 100-foot buffer are , depicted in Figures 2 through 4. The development of facilities within the 100-foot buffer zone presents the potential ' for indirect impacts to adjacent wetland resource areas during and following construction. During construction, impacts can result from erosion of upland soils and subsequent siltation of wetlands. Following construction, impacts can occur due to changes in surface hydrology and/or the inappropriate use and management of fertilizers and pesticides. 5.0 Mitigation of Impacts - Activities in Wetland Resource Areas ' The only activity to be conducted within a wetland resource area which will result in 6 , i ' the destruction and/or the impairment of the area is the proposed removal of ' approximately 4,230 square feet of canopy vegetation in wooded swamp wetlands E and L to permit play-over on the 7's, 14th, and 15`s fairways. This loss of canopy habitat will be mitigated through the planting of 20 red maple saplings within the ' wetlands adjacent to the locations of the clearings. It is anticipated that, upon maturity, these red maples will provide at least 5,000 square feet of canopy habitat. 6.0 Mitigation of Impacts - 100-Foot Buffer Zone The mitigation of potential impacts to result from the construction and operation of facilities within the 100-foot buffer zone will be implemented in two phases: the construction period and the post-construction period. During the construction period ' the focus will be on the control of soil erosion and prevention of siltation of wetlands and water courses. During the post-construction period the focus will be on the prevention of flooding and prevention of the release of pollutants in storm water ' runoff to wetlands and water courses. Construction Period ' All construction activities on the site will be conducted in conformance with the terms and conditions of a comprehensive storm water pollution prevention plan. This plan, which includes specifications for the installation and maintenance of soil erosion and sediment control devices, the implementation of erosion control ' procedures, and inspections and record-keeping, is presented as Attachment 2 to this Notice of Intent. The storm water pollution prevention plan has been developed in conformance with the NPDES General Permit for Storm Water Discharges from ' Construction Sites, as specified in the Federal Register Vol. 63, No. 31 dated Tuesday, February 17, 1998 (57 FR 44412). ' Specific erosion and sediment control devices to be utilized at the site during construction include: ' • Silt Fence, • Temporary Swales, • Catch Basin Filter Baskets, • Sediment Basins, • Hay Bale Catch Basin Filters, ' • Stabilized Construction Entrance, and • Stone Apron Velocity Reducers. ' Silt fencing will serve as the principal barrier to the discharge of sediments to wetland resource areas, roadways, and adjacent properties. As such, the fencing will be installed throughout the site between the areas of construction and adjacent 7 wetlands. Temporary swales will be used to divert stormwater from undisturbed ' areas away from disturbed areas and as slope breaks or interceptors to reduce the ' length of continuous slope disturbance. Minimizing the length of disturbed slope is essential to controlling erosion at its source. Catch basin filter baskets will be installed in all catch basins in the proposed clubhouse and maintenance area parking ' lots concurrent with the installation of the basins. The baskets will function to prevent the discharge of settleable silts and other solids to the drainage system until such time as pavement has been laid. A total of 40 sediment basins will be developed during the construction period. Each of the basins has been designed to retain at least 1,800 cubic feet of runoff per acre of tributary area. Sediment laden runoff from disturbed areas of the site will be directed to these basins prior to ' flowing to wetlands. Sediments will settle out of suspension in the basins thereby reducing reliance on perimeter silt fence controls. As with the catch basin filter baskets, hay bale catch basin filters will function to prevent the discharge of silts and ' other solids to drainage facilities; however, the hay bale filters will be used to protect field drain inlets on the golf course rather than catch basins in parking lots. Stabilized construction entrances will be provided at each construction access point ' (i.e., the end of Glen Road and the end of Granite Street). These entrances will be installed prior to the initiation of clearing and earthwork activity and will function to ' minimize the tracking of soils onto area roadways by vehicles exiting the site. Stone apron velocity reducers are designed to prevent the scouring of soils at new drain outfalls. Velocity reducers will be installed concurrent with the construction of the drain outfalls. The proposed locations for the installation of all erosion and sediment control devices are indicated in Figure 4. Details of each device are provided in Figures 14 through 26. ' Post-construction Period Throughout the operational life of the project, storm water runoff from the site will , be managed so as to ensure that there will be no increase in the peak rate of runoff to off-site areas during all storms up to and including the 100-year, 24-hour event. All ' supporting hydrologic computations are provided as Attachment 3 to this Notice of Intent. The minimization of pollutant loadings from the constructed project to surface ' waters, including wetlands, is the second focus of post-construction mitigation efforts. Potential sources of pollutant loads include runoff from the paved parking ' lots and the application of fertilizers and pesticides in the maintenance of the golf course. The results of the Nationwide Urban Runoff Program (NURP) published by the U.S. Environmental Protection Agency in 1983 indicate that storm water runoff ' from paved surfaces such as roadways and parking areas typically contain concentrations of such pollutants as hydrocarbons, suspended sediments, nitrogen ' and phosphorus (i.e., nutrients), and heavy metals (e.g., lead and zinc). The uncontrolled use of fertilizers and/or pesticides in the maintenance of a golf course or 8 ' any other land use (e.g., residential, agricultural or commercial) can have significant impacts on the quality of receiving waters. To minimize the potential for pollutant releases, the proposed golf course has been designed and will be managed according to a fully integrated and comprehensive water quality management program. The program consists of three basic elements: ' source reduction, application controls, and release controls. A key component of the water quality management program is the implementation of the Turf Management Plan presented as Attachment 4 to this Notice of Intent. The Turf Management Plan includes specifications concerning turf species to be established on each area of the golf course, a proposed fertilization program for each phase of turf development, descriptions of proposed cultural and mechanical management activities (e.g., irrigation, mowing, topdressing, dethatching, etc.), and an integrated pest management (IPM) protocol. The following are summary descriptions of the three water quality management program elements. In designing and implementing this ' program these elements have been and will be applied in the direct sequence presented herein. Source Reduction Source reduction, as it relates to water quality, refers to efforts designed to create ' conditions which have the effect of minimizing the need for pesticide and fertilizer use at the site. The need for pesticide and fertilizer usage in the maintenance of golf courses is a function of the degree of environmental stress affecting the health of the ' turf and the tolerance of the turf species to accommodate that stress. In other words, the greater the environmental stress experienced by the turf, the greater the need for ' pesticide and fertilizer usage; similarly, the less tolerant the turf species are to accommodate that stress, the greater the need for fertilizer and pesticide usage. Accordingly, source reduction efforts have been focused on the identification of ' actions which reduce environmental stress and on the selection of turf species for the golf surfaces which are compatible with the environment of Essex County, tolerant of the type and intensity of use anticipated at a public golf course, and inherently ' resistant to disease and pest infestations. The principal, controllable sources of environmental stress affecting turf are ' moisture, soil compaction, degree of sun exposure, and air circulation. These sources can be controlled through the implementation of a variety of design and/or "cultural" management practices. Of these sources, the one with the greatest effect on turf health is moisture. Too much water is as stressful to turf as too little water. The application of water to the turf must be carefully controlled to minimize this stress and, thus, the vulnerability of the turf to pest and disease infestations. The ' application of irrigation water at the proposed golf course will be managed through the use of a state-of-the-art, computerized irrigation system. This system, which will include precipitation monitoring equipment, will be programmed to respond to the ' 9 specific needs of the turf on each given day. The system also will have the flexibility and zonation features to permit the course superintendent to adjust applications within specific locations. Use of this system will ensure that optimum moisture levels are maintained in a way which minimizes turf stress throughout the course. Soil compaction, a result of intense turf use, will be alleviated through the use of ' aerification equipment. This equipment opens voids in the turf and soil permitting ' the exchange of oxygen with turf roots and greater water infiltration. Solar exposure and air circulation are stress sources which have been addressed in the design of the course layout and in the width of proposed turf areas. Each hole, particularly the ' green and tee areas, have been located and designed to have adequate solar exposure. Also, where tree clearings are proposed within the site's existing non-wetland wooded areas, the clearings are designed to be wide, or open, enough to allow proper air circulation across the turf surfaces. The selection of turf species for use on golf play surfaces is a primary consideration ' in the design of any course. To produce a quality course, the selected species must form a playable turf, appropriate to each type of play surface, and a turf which is resistant to substantial foot traffic pressure and frequent low mowings. In the ' selection of turf species for use at the proposed Peabody municipal golf course, the additional factors of regional compatibility, low to moderate fertilization demand, and disease/pest resistance have been considered. The selected turf species for ' installation at the golf course are specified in the Turf Management Program presented as Attachment 4. Application Controls Application controls are procedures designed to regulate the actual application of , pesticides and fertilizers so as to reduce their use in the golf course maintenance program. For much of this century, golf course management activities have focused , on the preventative application of fertilizers and pesticides to ensure a healthy, disease and pest-free turf. This approach is similar to that adopted by most suburban homeowners who are intent on establishing and preserving a lawn which is free of , defects. While such a program is easy to implement and can provide certain guarantees, it also frequently results in over-usage of chemical substances, thereby maximizing the potential for uncontrolled release to surface and ground waters. , Rather than adopting a generalized,preventative fertilizer and pesticide application program, maintenance activities at the Peabody municipal golf course will be ' undertaken in conformance with the protocol specified in the Turf Management Plan presented as Attachment 4. With regard to fertilizers, applications will be made based on the results of soil and plant tissue analyses. This is not to say that a basic annual fertilizer application program will not be necessary; rather, it means that the application program will be based on the actual needs of the turf at the specific site of 10 , 1 application and that supplemental applications will be site-specific. With regard to ' pesticide applications, all such applications will be made as an element of an integrated pest management (IPM) program. IPM programs represent the state-of- the-art in turf pest management in that they are customized with inherent flexibility ' designed to address the specific disease and pest problems experienced at a given site. An IPM program is one which seeks to anticipate the full range of physical, cultural, and biological factors affecting the development of pest populations and ' incorporates controls to address each of the factors. The result is a control program which relies on a diverse range of control mechanisms and less on a single mechanism, such as chemical pesticide application. ' At the Peabody municipal golf course, the IPM program will include the implementation of a full range of cultural, management, and biological controls designed to reduce the need for and/or the extent of chemical pesticide applications. These controls include those discussed above under the heading of Source Reduction ' together with the adoption of a threshold/response pesticide application strategy and the use of target specific pesticides. The IPM program includes specifications for the collection and maintenance of records of pesticide applications, the targets of those ' applications, and the effectiveness of the applications. Such record keeping will provide the course superintendent with the long-term, site-specific data which is critical to the development of a threshold/response strategy. By minimizing the use of chemical pesticides to only that necessary to maintain the turf in a healthy condition, the potential for release to surface and ground waters can be minimized. ' Release Controls Although the project has been designed to minimize the need for fertilizer and ' pesticide applications through source reduction efforts, and will be maintained in accordance with an IPM program designed to reduce the application of chemical pesticides, the use of both fertilizers and pesticides is vital to the proposed maintenance program. Given this, the third element of the water quality management program consists of procedures and devices designed to control the release of any applied substances or their residues to on- and off-site water resources. Release controls also function to reduce the discharge of pollutants typically associated with runoff from paved parking areas. These release controls include both management controls and structural controls. Management control efforts include the use of least- impact substances in meeting turf nutrient requirements and best available controls for the control of pests and diseases. They also include procedures designed to minimize the potential for release following applications. Structural control devices, also referred to as best management practices (BMPs), are constructed facilities which function to filter or otherwise enhance the removal of pollutants from storm ' water through settlement and physical retention. 11 The use of least-impact fertilizer materials and best available pest/disease controls is a critical element of the release control strategy. Least-impact materials and best available controls are those which provide for the achievement of the desired turf quality and health while representing the least potential for adverse impact to water resources and/or non-target organisms of all viable options. The Turf Management ' Program specifies the use of such least-impact substances as slow-release nitrogen compounds and pesticides with relatively short half-lives and/or low water solubility. The use of slow-release nitrogen compounds will ensure that this vital nutrient is ' released to the turf at a rate consistent with the rate of demand. Pesticides which exhibit short half-lives quickly degrade within the soil and accumulated thatch and, therefore, are less subject to release to water resources. Pesticides which exhibit low ' water solubility are less likely to be carried in storm water runoff. Pesticides will be used at the Peabody municipal golf course only to the extent that they represent, singly or in combination with other efforts, the best available control for a given pest or disease. Only pesticides registered for use in the Commonwealth of Massachusetts will be applied to the course and applications will be made in strict , conformance with label instructions. The proposed storm water collection and management system incorporates several ' structural elements which constitute "best management practices" (BMPs) for the control of runoff pollutants. It has been reported by several researchers that BMPs are very effective at removing residual pollutant loadings in storm water (Schueler ' 1987, Metropolitan Council of Governments 1983, Environmental Protection Agency 1983, Driscoll 1983, Kercher et al. 1983, and Wong and McCuen 1982). In addition to their pollutant removal benefits, BMPs generally are "natural' removal ' systems which require relatively little maintenance and blend with the natural landscape. In designing this system, the project engineers have focused on the removal of pollutants from the "first flush" of runoff(i.e., first one-half inch of ' runoff from all cleared and/or constructed surfaces). The "first flush" of stormwater runoff from constructed surfaces has long been recognized by researchers to be that portion of total runoff volumes likely to contain sufficient quantities of pollutants to be of significance to the maintenance of water quality. Runoff volumes generated subsequent to the "first flush" are essentially clean relative to runoff generated from natural, unaltered surfaces. The proposed storm water collection and management system incorporates infiltrator ' drains, vegetated swales, vegetated filter strips, catch basins with deep sumps and oil and grease trap hoods, and detention basins as structural BMPs. Each of the incorporated BMPs functions to remove runoff pollutants by enhancing or promoting , the physical settlement of particles. Biological uptake of nutrients also is a key removal mechanism in infiltration/detention basins, wet retention basins, vegetated swales, and vegetated filter strips. Proper design and maintenance of BMPs is , critical to their functioning. The specific design characteristics and maintenance requirements of each of the BMPs are as follows. 12 1 Infiltrator Drains Infiltrator° drains will be used as discharge points for all underdrainage from greens and tees located within 100 feet of a wetland boundary. Infiltrator°drains consist of a single length of standard capacity Infiltrator chambers installed in conformance with the stormwater design specifications developed by Infiltrator Systems, Inc. of Old Saybrook, Connecticut. All such drains will be located at least 30 feet from the edge of a wetland. Infiltrator°drains are high-capacity infiltration systems designed ' to provide for subsurface discharge of storm water. Infiltration technology has been found by many researchers to provide a high level of pollutant removal through filtration, absorption, and oxidation by soil micro-organisms. Once installed, Infiltrator° drains generally require no maintenance. Vegetated Swales Vegetated swales will have a minimum bottom width of four feet with side slopes not exceeding 3:1. Vegetated Swales will be vegetated with a dense growth of Reed Canary grass or KY-31 Tall Fescue immediately following their construction. Swales will be mowed weekly to maintain a height no greater than 12 inches nor less than six inches. During mowing, accumulated debris and litter will be removed. Each swale will be inspected annually as to its overall stability and condition. Spot reseeding and weed control will be undertaken as necessary and side slopes will be repaired when damage is observed. Vegetated Filter StriM Vegetated filter strips include both natural and man-modified areas which provide a vegetated filtering medium for sheet flow runoff. Natural filter strips consist of areas ' of retained woodland and/or meadow between golf surfaces and adjacent wetlands and water courses. Man-modified filter strips will be provided in areas where the retention of a minimum 20-foot deep natural vegetated strip is not practical (e.g., where fairways are proposed to cross wetlands or water courses and where grading precludes the retention of existing vegetation). Natural filter strips will be maintained in their current condition. Man-modified strips will be a minimum of 20 feet deep and will be vegetated with a dense growth of Annual ryegrass (15% Jamestown chewings fescue (25% and Reliant hard fescue (60%).. At a minimum, filter strips will be inspected annually. All debris and litter will be removed upon detection. Areas which exhibit erosion damage or channel development will be repaired and reseeded to restore sheet flow. Mowing of man-modified strips will be conducted as necessary to maintain a height of six inches. Fertilizer applications to man-modified filter strips will be made only as necessary to maintain a dense turf growth. No pesticides will be applied to the vegetated filter strips. ' 13 Catch Basins Runoff from the clubhouse and maintenance area parking lots will be collected in catch basins equipped with four-foot deep sumps and oil and grease trap hoods. Catch basins will be inspected twice annually (in the fall and spring) and cleaned of ' accumulated debris when the capacity of the sumps has been reduced by 50%. 7.0 Compliance with Stormwater Management Guidelines r Consistent with the stormwater management guidelines developed by the Massachusetts Department of Environmental Protection and Office of Coastal Zone Management (1997), stormwater management facilities have been designed to remove and capture at least 80 percent of the suspended sediment loadings from new impervious surfaces on the site. These new impervious surfaces are limited to the proposed maintenance building and parking area, the proposed clubhouse and parking area, and the proposed paved cart paths. Calculations demonstrating compliance with this 80 percent removal standard are provided in Attachment 5.

Signature Date Title Company PEABODY MUNICIPAL GOLF COURSE Stormwater Pollution Prevention Plan-10 ATTACHMENT 3 Hydrologic Computations 1 , �i 1 i DECOULOS & COMPANY ENVIRONMENTAL ENGINEERING&LAND PLANNING MEMORANDUM DATE: Wednesday, September 23, 1998 TO: Peabody and Salem Conservation Commissions 0 FROM: James J. Decoulos, PE, LSP RE: Stormwater Modeling of Proposed Peabody Municipal Golf Course Attached is the stormwater quantity modeling documentation that supports the design 1 of the proposed golf course. Stormwater quality calculations are provided in Attachment 5. The Site consists of two parcels of land; the parcel to the south owned by the City of Peabody and the parcel to the north owned by the Eastman Gelatine Corporation (see attached Figure W1). Eastman Gelatine formerly disposed of lime waste in five separate lagoons (Lagoon 0 through Lagoon 4) on its property. In the early 1980s, Eastman began closing and capping the lagoons under the direction of Haley & Aldrich of Cambridge, MA (H&A). H&A was primarily concerned in stabilizing the material used to fill the lagoons and ensuring that the closure would be permanent. H&A engaged Vanesse/Hangen Engineering, Inc formerly of Boston, MA (VHE) to design the stormwater controls at the lagoons. VHE undertook a detailed watershed and routing analysis to detain the peak flow rates from 100 year storms. The Technical Memorandum summarizing the work is at the back of this Attachment. The full work was described in the report entitled Technical Memorandum, Hydrologic Study of Lime Lagoon Conceptual Closure Plan, Peabody, Massachusetts, by Haley & Aldrich, Inc. The controls for the lagoons have been operating successfully since the mid 1980s. The controls consist of two detention basins and an existing wetland system to control peak flow rates. The area over the lagoons is currently lightly vegetated and disturbed in many areas from the use of off-road motorcycles. The proposed condition (mostly grassed fairways and fringed grassed areas) will greatly improve the absorption capacity of the surface. As a result, the safety factor of the VHE design will improve and the grassed areas will provide additional stormwater quality benefits to the area. The prior work in modeling the stormwater impacts over the lagoons will be assumed to be sufficient. The modeling of the rest of the property around Meadow Pond, Sidney's Pond and the Cedar Grove Reservoir is the focus of these calculations. 248 ANDOVER STREET, PEABODY, MASSACHUSETTS 01960 TEL: 978 532 8154 FAX: 978 5310936 WWW.DE000LOS.COM Page 2 of 2 Peabody Municipal Golf Course Stormwater Modeling Wednesday, September 23, 1998 The remainder of the Site has been divided into six basins. They are described on Figure W1 as Sub-Basins 1 through 5 and Sub-Basin 3A. Sub-Basin 3A is currently flowing into a wetland resource to the northwest and ultimately into the public water supply of Spring Pond. In order to minimize impacts to the water supply, the grading of the area within Sub-Basin 3A has been designed to re-route stormwater flows to the northeast, into Sub-Basin 3 (see Grading Plan, Figure 3). The soil conditions outside of the lagoons are described by the U.S. Natural Resources Conservation Service (NRCS) as predominately Chatfield-Hollis-Rock outcrop complexes, ranging in slopes from 3 to 35 percent. Bedrock outcrops are frequently encountered and the soil cover is minimal. In some areas, soil cover is not sufficient to support the growth of mature, large trees. Due to the thin soil cover, the Curve Number (CN) used to model the pre-existing condition was 69. The selection of this number was based on the limited infiltration capacity of the subsurface and the relatively light wooded condition. If stormwater is not taken for evapotranspiration, it will likely ride along the top of the bedrock surface and seek a surficial discharge into either Strongwater Brook, Sidney's Pond or Meadow Pond. s The proposed golf course will be requiring significant amounts of suitable fill material from off-Site in order to shape the course as planned. Together with the extensive seeding that will take place, the CN for the proposed condition should actually be less than the existing condition. A CN of 65 has been selected for the composite soil condition around the course. The time of concentration for the proposed conditions is longer than the existing conditions. This is justified by the ultimate density of the proposed cover in comparison to the existing condition and the wide use of dry detention basins around the fairways. The attached documentation includes the existing 10 year and 100 year conditions for each of the basins; the proposed 10 year and 100 year conditions; and the combined modeling of Sub-Basins 3 and 3A.

SUBJECT: Hydrologic Study of Lime Lagoon Conceptual Closure Plan Peabody, Massachusetts INTRODUCTION Eastman Gelatine Corporation is seeking to provide permanent closure for five lagoons on its property south of Washington Street in Peabody (Refer to Figure 1 , Project Locus) . The lagoons were filled over a 50-year period with 10 to 20 ft. WW! of disposed lime waste, covering an area of approximately 20 acres . A conceptual closure plan which is designed to control odors , seepage, and storm water runoff while maintaining stable lagoon surfaces for pedestrian and light vehicle traffic, was developed during initial studies in 1983 . A key element of the conceptual lagoon closure plan is to cover the lagoons with a low-permeability cover. The low-permeability cover would have the effect of dramatically reducing rainfall infiltration into the lagoons , thereby effectively eliminating the primary source of lagoon seepage . An assessment of existing site hydrology and, assuming full plan implementation, the impact of low-permeability lagoon �I covers on the future proposed site hydrology is the subject of this memorandum. Calculations which evaluate existing and future site hydrology with proposed changes are provided in the Appendices . Affiliate. Branch Office' H&A of New York Haley&Aldrich,Inc. Rochester,New York Portland.Maine K®A Eastman Gelatine Corporation -2- 13 July 1984 SITE CONDITIONS AND GEOLOGY The area surrounding the lagoon site is generally characterized by a thin layer of relatively low-permeability alluvium and/or dense glacial till overlying shallow bedrock. The site topography has been modified by filling activities in the area of the lagoons . The immediate lagoon vicinity consists of relatively complex site conditions , topography and surficial geology. The highest topographic features (E1. 100+) consist of three bedrock-controlled hills which encircle the lagoons on three sides . Hills surround Lagoon 4 to the east, south, and west, and another hill rises at the intersection of dikes surrounding Lagoons 2, 3 and 4. The surfaces of existing contiguous Lagoons 1 through 4 vary in elevation from E1 . 70 in Lagoon 3 to E1. 84 in Lagoon 4. The surface elevation of Lagoon 0 varies between E1 . 54 and E1 . 62 . A comparatively low wetland area exists to the north of Lagoons 1, 2 and 3 ; surface elevations in this area vary between approximately E1. 59 and 62 .5 . An old cinder and ash man-filled dike, varying in elevation from E1 . 63 to E1 . 66 and semi-circular in shape, exists in the wetlands north of Lagoons 2 and 3. A drainage channel runs through the wetlands, along the toe of the man-filled north dike of Lagoon 1 into a culvert under Hingston Street . In the wetland area, surface water drainage patterns have resulted in shallow alluvial and swamp deposits . This area is vegetated primarily with hardwood trees and brush. EXISTING HYDROLOGY o REGIONAL The area of the lagoons is completely contained in the Meadow Pond drainage subbasin of the North River drainage basin, as shown in Figure 1. The Meadow far Pond subbasin is relatively small and drains into the Strongwater Brook subbasin northeast of the lagoons . Sidney' s Pond is located in the Tapley Brook subbasin, which drains into the Goldthwait - Brook subbasin. The confluence of Goldthwait and Strongwater Brooks is in the center of Peabody, approximately 5 ,000 ft. (0.9 miles) northeast of the lagoons . Water then flows into the North River which drains into Salem Harbor. ' K®A Eastman Gelatine Corporation -3- 13 July 1984 Drainage within the Meadow Pond subbasin is shown on Figure 2. Surface runoff drainage divides isolate the lagoon area from Sidney' s Pond to the west and Strongwater Brook to the east . Water on the surfaces of the lagoons is trapped within the encircling dikes and bedrock hills so that no runoff presently occurs from the lagoons themselves . The trapped surface water is pumped to a sanitary sewer, while a small fraction percolates into the sludge to eventually exit as seepage through the dikes . Seepage and surface water drainage which is not pumped to sanitary sewers eventually enters the Meadow Pond area brook and exits through the northeast corner of the subbasin to enter Strongwater Brook. o WETLANDS A detailed assessment of existing drainage areas , and approximate limits of Eastman Gelatine property are provided in Figure 3 . The existing wetland area, owned by Eastman Gelatine, receives rainfall runoff from a drainage area of 29 .5 acres . A 12-in. _ diameter vitreous tile pipe , hereinafter referred to as the 'wetlands culvert' , passes under Hingston Street and Lagoon 0 and is the sole outlet of surface water from the wetlands . Presently, no runoff from Lagoons 1, 2 , 3 and 4 directly enters the wetland area. To determine the present storage capacity in the existing wetland area, Vanasse/Hangen first used normally-accepted criteria based on the Soil Conservation Service (SCS) method. However, more conservative historical data for equivalent runoff precipitation depths were recommended by the Peabody Conservation Commission '1 Consulting Engineer Joseph Finegan and were used to establish the worst case condition in the final calculations in Appendix A. This more conservative method assumes starting water surfaces between El. 60 .0 and El. 61 .0 within the wetland area for the final computations . Only storage above El. 61 .0 was finally considered. Furthermore, to be still more conservative, the existing wetlands culvert was considered blocked , with no discharge allowed to,, flow through this r G K®A _ Eastman Gelatine Corporation -4- 13 July 1984 line. Using this worst case analysis of present conditions, calculations indicate a peak runoff rate ' into the wetlands of 87 .0 cubic feet per second (cfs) , resulting in a runoff volume of 11 .0 acre-feet , which brings the water surface to E1 . 62 .6 for a 100-year storm. This analysis indicates the need to control any additional runoff that may be created by future closure efforts by use of detention areas before being directed to the wetlands . Discharge-rating curves for existing conditions in " the wetlands are included on pages 13 and 14 of Appendix A. An area-capacity curve for the existing wetlands is on page 15 of Appendix A. Yo LAGOON 0 The existing drainage area including Lagoon 0 is 2 . 1 acres , which is the smallest drainage area on site . Rainfall presently infiltrates the sludge surface to a limited depth. Rainfall from high intensity storms flows laterally towards the east and south dikes of the lagoon rather than infiltrating into the underlying sludge . The runoff then seeps through the relatively pervious cinder and ash dikes . Seepage from the dikes is imperceptable during most precipitation events . Lagoon 0 runoff quantities are estimated in Appendix B calculations . The calculated runoff from the area during a 100-year storm varies from 0 .2 acre-ft. using the rational formula method, to 0 .7 acre-ft . using the SCS method. (The rational formula is probably a better indicator, as the SCS method is not directly applicable to 2-acre areas . ) Both analyses indicate that the runoff from Lagoon 0 is relatively small . PROPOSED CONSTRUCTION Once fully implemented, the proposed closure plan will cover each lagoon with a low-permeability material . A conceptual site grading plan is provided in Figure 4. When the lagoons are covered, surface water will be directed towards the wetland area which is entirely owned by Eastman Gelatine. Y AGA Eastman Gelatine Corporation -5- 13 July 1984 It is desired to maintain the maximum water level in the wetlands below E1 . 62 .5 during a 100-year rainfall event . Calculations (page 4, Appendix G) indicate that, if all lagoon runoff is allowed to flow directly into the wetlands and the wetlands culvert is blocked, the wetlands water level would rise to El. 63 .6 . Since this level is above the desired maximum wetlands operating water level , it is evident that the runoff from the closed lagoons must be routed to detention areas prior to entering the wetlands . To control the rate of release of lagoon runoff into the wetland area, two detention basins , Detention Basin 1 and Detention Basin 2, are proposed to collect and store the runoff. A description of the key elements of the proposed construction plan follows . o LAGOONS 1 , 2 AND 3 Lagoons 1, 2 and 3 will be graded to form a central trough in each lagoon to direct runoff to Detention Basin 1 . Runoff will exit each lagoon over existing but lowered embankments . Spillway areas will be covered with riprap , and appropriate siltation and erosion controls will be employed. a7 o LAGOON 4 Lagoon 4 will be graded to direct runoff to its existing lowest point, in the southwestern end of the lagoon. Runoff will enter a control structure at that point, and pass through a 36-in. reinforced concrete pipe to Detention Basin 2 . o DETENTION BASIN 1 The 2- to 4-ft. high cinder and ash dike which currently exists in the wetlands north of Lagoons 2 and 3 will be integrated into the Detention Basin 1 perimeter dike . The current dike elevation (El. 62 to 66) will be raised to a finish grade at El . 66 without extending the lateral limits of the existing dike into the wetlands . A minimum width of 12 ft . will be maintained at the top of the dike, and sideslo.pes will be no steeper than 2 horizontal to 1 vertical to minimize' encroachment into the wetlands . Inside the confines AAA Eastman Gelatine Corporation -6- 13 July 1984 of the existing dike, the natural vegetation and I ; topography will be only minimally disturbed. Minor disturbance would result from construction of outlet control structures , and minor drainage improvements made in the small, confined lowland area north of Lagoon 3. A man-filled dike projecting west of the Lagoon 2 north dike would also be removed. o DETENTION BASIN 2 Detention Basin 2 will be constructed west of the Lagoon 3 confining dike. Natural topsoil , loess and glacial till deposits in the area will be excavated --.. down to E1 . 64, to provide an appropriately sized basin. Excavated materials can be used as lowpermeability lagoon cover soils and/or topsoil vegetative cover for lagoon closure. Use of this on-site material will reduce the trucking requirements for off-site materials onto the site . A large number of boulders which are unsuitable for placement on lagoon surfaces are, however, likely to be encountered in the glacial till . These will either be disposed of or left in place. Detention Basin 2 dikes and berms will have minimum 3 horizontal to 1 vertical sideslopes . Northern perimeter dikes would be constructed using soils excavated from the basin. Vegetation will be -• established on all exposed soil surfaces . o LAGOON 0 ' Lagoon 0 will also be covered with a low-permeability cover and graded to form swales on the lagoon surface. The swales would lead to the east lagoon embankment, where a check dam will be provided to retard runoff through the embankment . A schematic detail of the check dam, which consists of a pervious zone of 4 to 12 in. rock, is provided on page 3 of Appendix J . o GRADING SOUTHEAST OF LAGOON 1 To the southeast of Lagoon 1 , the existing steep rubble fill slope will be regraded to stabilize this - slope and reduce erosion. AAA Eastman Gelatine Corporation -7- 13 July 1984 POST-DEVELOPMENT HYDROLOGY o FLOW INTO DETENTION BASINS Therain d i age areas resulting from the proposed site grading plan are indicated in Figure 3. These drainage areas were used in hydrology analyses to size the detention basins . Drainage analysis calculations are provided in Appendix C for Lagoons 11 2 and 3, and in Appendix D for Lagoon 4. Drainage analyses for the areas around and including Lagoons 1, 2, 3 and 4 were computed by the standard SCS method, using the 100-year storm event . (Note: In this case , the SCS method coefficients are more conservative than those suggested by Mr. J . Finegan, and were therefore used to provide an even greater safety factor.) For Detention Basin 1, the drainage area consists of 1 16 .7 acres which includes Lagoons 1, 2 and 3 and produces a volume of runoff of 6 .3 acre-feet and a discharge to the basin of 75 .4 cfs for a 100-year storm. The storage capacity of the basin is 7 .4 acre-feet . For the 100-year storm event, a closing or blockage of the outlet pipe from the basin would provide 0.6 ft. freeboard height, exceeding the 0 .5 freeboard suggested by Mr . Finegan. The proposed Lagoon 4 drainage area is 14. 2 acres , and produces a runoff volume of 4.8 acre-feet and a discharge of 62 .0 cfs for a 100-year storm. Runoff will enter a drop inlet manhole with double grate cover at the proposed low point of Lagoon 4. (See Appendix D for details .) Lagoon 4 runoff will be piped into Detention Basin 2 through an approximately 600-ft. long, 36-in. diameter reinforced concrete drain pipe. This drain will discharge a peak flow of 53.0 cfs for the 100-year storm. Therefore, using the grading plan in Figure 4, the resulting temporary back-up of runoff on Lagoon 4 could potentially reach a maximum E1 . 75 .9 for a 100-year storm. This backup would however be released to Detention Basin 2 within 1 to 2 hours . TM K®A M Eastman Gelatine Corporation -8- 13 July 1984 The storage capacity of Detention Basin 2 is 5 . 7 acre-feet. For the 100-year storm event, a closing or blockage of the outlet pipe from the basin would provide 0 .8 ft. of freeboard. o FLOW INTO THE WETLANDS Discharge from both detention basins will be moderated by control structures within the basins , as indicated on page 4 of Appendix J . The design detail also includes a sluice gate valve and 12-in. diameter outlet pipe constructed in series . When - closed, the sluice gate valve will prevent any discharge from entering into the wetland area. Gates will be left completely open until such a time ,,. as the water in the wetlands rises to E1. 62 .0 ; gates would then be closed until the water in the wetland area subsides . Appendix E contains outlet control calculations for Detention Basin 1 . Calculations indicate that a , fully open 12 in. pipe would moderate the discharge to 8 .9 cfs into the wetlands . When the water elevation exceeds El. 62.0 in the wetlands and the sluice gate is closed for the 100-year storm, the maximum runoff elevation in the basin would rise to El . 65 .4, occupying 85 percent of the available detention basin volume . Outlet control calculations for Detention Basin 2 are in Appendix F. A fully open 12-in. discharge pipe would produce a maximum discharge of 8 .7 cfs to the wetlands . When the sluice gate is closed for the 100-year storm, the maximum runoff elevation in the basin would rise to E1 . 69 .2, occupying 85 percent of the available detention basin volume. o EFFECTS ON THE WETLANDS r. Vanasse/Haugen evaluated the effects of flows from the detention basins into the wetlands using two independent cases , which assume either of the following: 1 . wetlands culvert is completely blocked (worst -- case assumption for the proposed plan, without time effects) K®A �? Eastman Gelatine Corporation -9- 13 July 1984 2 . wetlands culvert is open (realistic case assumption for the proposed plan, with time effects) Precipitation events and other parameters were varied to examine both cases . These results are discussed below. 1 . Wetlands Culvert Blocked: Appendix G contains calculations for runoff flows into the wetlands with a completely blocked culvert. The wetland water level would rise to E1 . 63 .6 , if detention basins were not used using the same runoff intensity assumptions as the existing conditions evaluation. This calculation indicates the need for the detention basins in the worst case. Next, rainfall events ranging from 2 .0 in. to 6 .5 in. in a 24-hour period were used to determine water elevations in each detention basin and in the wetlands , neglecting time effects . Each detention basin may operate independently. Therefore, water levels in the wetlands were determined assuming that one, or the other, or both detention basins releases runoff into the wetlands from a particular storm. Results of this analysis (Appendix G, page 6) indicate that even with a blocked culvert, detention basin and wetland capacities are adequate for 100-year storm runoff storage without impacting adjacent properties . 2 . Wetlands Culvert Open: To provide a more realistic assessment of the impact of design storms on the wetlands , Vanasse/Haugen performed a hydrologic routing analysis for the lagoon site. This analysis assumes that the wetlands culvert and control structures are open. Time effects are taken into account. Design storms of 100-year frequency (6 .5 in./24 hr. period) and 25-year frequency (5.4 in./24 hr. period) were evaluated. Calculations are provided in Appendix H. K®A Eastman Gelatine Corporation -10- 13 July 1984 The results of the hydrologic routing analyses are summarized below: MAX. RUNOFF PEAK DIS- AREA ELEVATION (FT. ) CHARGE (CFS) 0 100-year storm -,; Detention Basin 1 63.4 7 .3 Detention Basin 2 68 .8 8 . 2 Wetlands 62 .3 7 .4J. 0 25-year storm Detention Basin 1 62.8 6.6 Detention Basin 2 66 .0 4.9 Wetlands 62 .0 7 .0 The hydrologic routing analysis determines that with the wetlands culvert and detention basin control structures open and a regular maintenance program established, serious flooding or significant increases in water surface elevations will not occur _ in the wetlands . To provide an even greater safety margin, sluice gate valves have been designed into the detention basin outflow structures so that the basins can be completely isolated from the wetlands in worst case conditions , if required. The gate -. valves from the two detention basins would be closed if the wetlands water level exceeds El . 62 .0 . The hydrologic routing calculations indicate that water levels in excess of El . 62 .0 would only be expected to occur for storms larger than a 25-year event. The need for detention basin gate valve closure would thus be limited to rare occasions . ;$ o DOWNSTREAM OF NORTH WETLANDS The wetlands culvert will continue to be used as the single wetlands drainage outlet . The culvert will be maintained as necessary for optimum pipe performance. East of Lagoon 0 and downstream of the wetlands culvert, the rate of runoff will be controlled primarily by the peak flow through the culvert . The K®A Eastman Gelatine Corporation -11- 13 July 1934 •� check dam detail on page 3 of Appendix J will handle Lagoon 0 runoff in a similar manner as presently exists . SUMMARY AND CONCLUSIONS The proposed lime lagoon closure plan includes covering the lagoons with a low-permeability cover, which will be graded to the wetlands north of the lagoons . To control the rate of flow into the wetlands , two stormwater detention basins will be constructed. Effluent from each basin will be moderated by the use of a control structure . A sluice gate valve will also be constructed in each basin to prevent flow into the wetland when required. The gate valves will normally operate in an open position, and will be closed only if the wetland water level reaches E1 . 62.0. Through the use of the proposed detention basin system, the stormwater management plan will effectively control the runoff from Eastman Gelatine' s lime lagoon site south of Washington Street, once this area has been fully closed. The stormwater management system protects residents both around and downstream of the wetlands .

Healthy turf is best able to withstand the stress of golfer traffic, combat pest and disease infestations, and respond favorably to efforts aimed at reducing the use of chemical fertilizers and pesticides in the management of golf courses. The natural characteristics of turfgrasses limit movement of pesticides and fertilizers into underlying soils and ground water. Thatch produced by the turf acts as an organic filter to chemically bind pesticides that otherwise might enter surface and ground waters. Also, turfgrass root systems are both extensive and fibrous, resulting in both the adsorption and absorption of pesticide residues which may penetrate the turf canopy and thatch layers. The purpose of this turf management program is to identify the fertilization program, cultural practices, and pest management procedures to be implemented during both the construction and long-term operation of the Peabody Municipal Golf Course. This plan has been drawn from the collective experiences of Cornish, Silva and Mungeam, Inc. and Sasaki Associates, Inc. in the design of golf facilities and that of agronomists, water quality scientists, and golf course superintendents in the maintenance of such facilities. A list of supporting references is provided at the end of this document. TURFGRASS SELECTION Extensive turfgrass breeding programs and research studies completed at a number of universities and agricultural research stations have resulted in the production of turfgrass varieties that are particularly well-suited for establishment on golf courses. The species/varieties of turfgrasses to be established at the Peabody Municipal Golf Course have been selected due to their recognized suitability for the proposed use, given considerations of hardiness, efficiency in water use, the climate and soils of the northeastern United States, natural pest resistance, and the level of anticipated use. Each of the selected species/varieties has been tested on established golf courses in Massachusetts. The selected species/varieties of turfgrasses to be established in each area of the proposed course are as follows. Surface Type Turf Seed Greens Bentgrass-Penncross (33%),Pennlinks (33%), South Shore (33%). 1 Tees Bentgrass- Penncross. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-I of 13 Surface Type Turf Seed Fairways Bentgrass- Pennlinks (33%), Penncross (33%), Penneagle (33%). Roughs and Practice Area Perennial Ryegrass (15%), Jamestown Chewings Fescue , (20%), Nugget Kentucky Bluegrass (20%), Glade Kentucky Bluegrass (20%), Touchdown Kentucky Bluegrass(25%). Turf Filter Strips Annual Ryegrass (15%), Jamestown Chewings Fescue (25%), Reliant Hard Fescue (60%). FERTILIZATION PROGRAM The availability of the basic growth nutrients of nitrogen, phosphorus, and potassium is essential to the growth of any vegetation species and turfgrasses are no different. Adequate quantities must be available to the turf at specific periods in its life cycle to stimulate and , maintain growth. These nutrients are available in the existing soils but must be supplemented to support the demands of turf. Supplemental inputs of nutrients are achieved through the implementation of a fertilization program. The focus of such a program is to deliver only those nutrients which are necessary to support suitable turf growth in a manner which both maximizes their availability to the turf and minimizes waste and the release of excess nutrients to surface and ground waters. A number of research studies on the leaching and surface runoff potential of nitrogen and phosphorus applied to turfgrasses have concluded with the finding that appropriate applications do not pose a risk to surface and ground water quality. Petrovic (1990), reporting on the results of research on nitrogen fertilizer applications, found that nitrate- nitrogen concentrations in ground water beneath turfgrass plots exceeded the drinking water standard of 10 ppm only in sandy soils and only if either high levels (i.e., greater than 3.0 lbs./1,000 square feet) of soluble nitrogen are applied or daily irrigation is practiced coupled with the application of water soluble nitrogen sources. Other recent research by Linde et al.(1994) has concluded with findings of no exceedences of the 10 ppm standard. Phosphorus release following turfgrass fertilizer applications has been found to be insignificant by a number of researchers. Young et al. (1985) reported that phosphorus rapidly becomes fixed in the soil profile and vertical movement in most soils ranges between 0.3 and 1.2 inches/year. Watschke and Mumma (1989) found that under the extreme rainfall conditions that actually were required to produce runoff from a healthy turf plot (i.e., 6.0 inches/hour) only 0.5 lbs./acre of phosphorus loss occurred. The results of virtually all research studies completed on the fate of nutrients applied to turf have supported adherence to the following general guidelines in order to minimize and/or eliminate the potential for any release of nutrients due to fertilizer applications on golf turf. 1. Irrigation should be limited to the replacement of lost soil moisture and the evapotranspiration losses of the turf. 2. When appropriate, nitrogen applications should be made using slow-release sources. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-2 of 13 3. All fertilizer applications should be timed to occur at the time of active plant uptake. r4. Applications should not be made immediately preceding a forecasted significant storm event. 5. Application rates should be limited to the documented needs of the turf given an understanding of site-specific soil deficiencies. Grow-In Period Fertilization Program Following the basic guidelines for fertilization, initial fertilization requirements will be based >� on the results of soil tests conducted on the final topsoil of the course and the known nutrient requirements of the selected turf species. Soils will be analyzed for pH, soil nitrogen reserves, calcium, magnesium, phosphorus, potassium, manganese, zinc, and copper availability and balance. The objective of the grow-in program is the rapid establishment of a high quality turf cover to minimize erosion potential and weed infestation. Accordingly, applications should be made as ' necessary to adjust pH to be within the range of 5.5 and 6.5 and up to 50 percent of applied nitrogen fertilizer should be of a water soluble form. At least 50 percent of applied nitrogen should be from a slow-release source (e.g., organic sources such as Milorgranite, Ringer, Sustane; isobutylidene diurea; methylene ureas; and coated ureas such as SCU, Polyon, Poly-S, and Sulfurkote-II). Turfgrass Establishment Period The turfgrass establishment period consists of the first and second years following the germination of the turf. The basic fertilization requirements during this period are as follows. These applications should be adjusted accordingly during this period if desired growth is not achieved or if the examination of foliage indicates that reduced applications would be suitable. 1 Golf Surface Nutrient Application Rates Nitrogen Phosphorus Potassium Greens 0.7 lbs/1000 sf/growing month based on soil tests based on soil tests Tees 0.75 lbs/1000 sf/growing month based on soil tests based on soil tests Fairways 320 lbs/ac/growing season based on soil tests based on soil tests Roughs 240 lbs/ac/yr based on soil tests based on soil tests Corn gluten meal will be applied to the fairways and roughs at a rate of 10 lbs./1,000 sq.ft. for crabgrass control. At this application rate, the corn gluten meal will supply one pound of nitrogen per 1,000 sq.ft. of surface area. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-3 of 13 Turfgrass Post-Establishment Period The post-establishment period consists of the life of the course subsequent to the first two years following germination of the turf. Fertilizer applications should be based on the results of analytical soil tests and examination of the condition of the turf. Estimates of anticipated application rates for this period are as follows. Golf Surface Nutrient Application Rates Nitrogen Phosphorus Potassium Greens 3 to 6 lbs/1000 sf/yr based on soil tests based on soil tests , Tees 3 to 6 lbs/1000 sf/yr based on soil tests based on soil tests Fairways 90 to 180 lbs/ac/yr based on soil tests based on soil tests Roughs 45 to 90 lbs/ac/yr based on soil tests based on soil tests , Fertigation System Fertilization during the turf establishment and post-establishment periods will be conducted through the use of a fertigation system. Fertigation is the process of fertilizing at low application rates through the irrigation system. Reporting on the results of a recent study of fertigation, Snyder et al. (1989) concluded that turf grass nitrogen uptake and subsequent plant growth was more uniform and the potential for leaching to groundwater greatly reduced under this process, as compared to a conventional fertilizer application process. CULTURAL MANAGEMENT PROGRAM Cultural practices refer to those activities involving the addition of materials to the turfgrass system for the purpose of stimulating or maintaining growth. These practices include irrigation, topdressing, fertilization, and the addition of such amendments as lime for pH adjustment and iron to prevent the development of iron chlorosis. As fertilization requirements are addressed herein as a separate section, this section on cultural management will focus on non-fertilization practices. Irrigation , The most significant controllable source of environmental stress to turf is moisture: too much water is as stressful to the turf as is too little water. If turf moisture is not adequately controlled, the resulting stress to the turf will make it more vulnerable to disease and pest infestations. The principal tools available to control moisture include the siting and construction of golf surfaces and the implementation of an irrigation program. Siting and construction practices, such as elevating tees and greens, providing suitable cross-surface ventilation, and installing appropriate drainage systems, are intended primarily to prevent the accumulation/retention of too much moisture. An irrigation system is intended to ensure the , provision of an adequate supply of moisture to offset losses due to evapotranspiration. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-4 of 13 The irrigation water demand of the proposed Peabody Municipal Golf Course is anticipated to be approximately 100,000 gallons per day as averaged over the entire 180-day irrigation season. This demand represents the anticipated evapotranspirative losses of the turf which will not be restored by normal precipitation. The source of this irrigation water will either be groundwater from an existing well owned by Eastman Gelatine Corporation or process waste water from Eastman Gelatine's facilities. The proposed irrigation system will be state-of-the-art, incorporating computerized controls and weather monitoring equipment. The computer controls will incorporate override capabilities which will allow the golf course superintendent to adjust delivery to each area of the course to respond to needs which may vary from day to day. The weather monitoring equipment will monitor and record air temperature, soil temperature, wind speed, wind direction, barometric pressure, rainfall, humidity, and solar radiation. The monitoring equipment will be linked to the irrigation system computer for ease in calculating actual daily evapotranspiration and irrigation water demand. To assist in determining the appropriate application, the superintendent should periodically obtain core samples of various turf areas. If water has not penetrated to a desired depth within six to eight hours following an irrigation, then the irrigation time should be increased. If the water has moved well beyond the desired depth within six to eight hours, then the irrigation time should be decreased. Topdressing Topdressing aids in thatch decomposition, lessens grain development, stimulates new shoot growth, encourages stolon rooting, and makes the ball roll true and faster. Although a small amount of thatch is desirable to provide a degree of resiliency, thatch is the greatest single limiting factor to the development of fast uniform greens. By mixing suitable topdressing materials with the organic thatch material, thatch decomposition can be enhanced and the formation of layers prevented. Also, topdressing with compost or a compost/mineral mix may aid in reducing the incidence of certain diseases. Studies conducted at Cornell University have demonstrated that monthly applications of topdressings composed of as little as 10.0 pounds of suppressive compost/1,000 square feet are effective in suppressing diseases such as dollar spot, brown patch, Pythium root rot, Typhula blight, and red thread. The recommended topdressing program for the Peabody Municipal Golf Course is as follows: Greens.....................0.20 cubic yards/1000 square feet up to six times per season ' Tees.........................0.25 cubic yards/1000 square feet up to four times per season Other Amendments ' Iron applications may be necessary to correct developing iron chlorosis. Applications at up to 2.0 ounces/1000 square feet should be made as necessary. Soil pH should be modified as necessary through the application of lime to achieve a level between 5.5 and 6.5. Other nutrients and mineral amendments should be made as necessary to respond to deficiencies detected through periodic soil sampling. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-5 of 13 MECHANICAL MANAGEMENT PRACTICES Mechanical management practices include mowing, dethatching, aerifying, spiking, and rolling. These practices establish and maintain appropriate turf height, prevent the excessive accumulation of thatch, enhance oxygen/root exchange, prevent excessive compaction, and ' improve green speeds. Mowing Regular mowing practices enhance turf density, color, texture, root development, wear tolerance, and other aspects of turf quality. As taller grass has a higher evapotranspiration rate, ' proper mowing can reduce the irrigation demand of turf. On the other hand, mowing grasses too short may produce undue stress which will make the turf more susceptible to pest and disease infestations. The recommended mowing practices for the Peabody Municipal Golf Course are as follows: Greens Tees Fairways Roughs Height(inches) 3/16 (0.19) 1/2 (0.5) 3/4 (0.75) 2.0-3.0 -Frequency 5-6 times/week 3 times/week 3 times/week Once per week Fate of Clippings Remove Remove Return Return Vertical mowing can be used to reduce mower induced grain on greens and thatch accumulation. Such mowing practices also can be used to break up the cores produced by aerification equipment (see aerifying). Dethatching Excessive thatch accumulation increases disease susceptibility of the turf; reduces tolerance to drought, cold and heat; and can restrict the movement of air, water and fertilizer into the soil layer. Thatch can be removed using a variety of mechanical equipment. As a general guideline, dethatching should occur when the thatch thickness increases to 1/2 inch on fairway areas or 1/4 inch on greens. Aerifying Aerification practices reduce soil compaction which, in turn, improves surface water infiltration, enhances root penetration and air exchange, and promotes nutrient uptake by the turf. Aerification is accomplished by coring of the turf/soil matrix. A variety of machines are available for this activity. Cores can be deposited on the turf surface and broken up to improve thatch decomposition. Aerification of greens typically is followed by topdressing to prevent recompaction of the turf. Spiking Spiking is useful in breaking up soil compaction and improving moisture infiltration and , root/air exchange. This practice can help reduce thatch accumulation by lifting the blades of grass prior to mowing. PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-6 of 13 , Rolling Light-weight rolling equipment may be used to smooth turf surfaces and increase green speed. When used during the summer growth months, rolling can permit the retention of greater turf ' heights, thereby increasing stress tolerance. Rolling should not be conducted more frequently than twice a week to prevent excessive soil compaction. INTEGRATED PEST MANAGEMENT ' All pest control activities at the Peabody Municipal Golf Course will adhere to integrated pest management (IPM) practices. IPM is an approach to pest control which seeks to anticipate and address the full range of physical, cultural, and biological factors affecting the development of pest populations at a given site. This approach does not seek, as a goal, the eradication of pest populations; rather, it seeks to prevent the growth of pest populations and/or disease infestations above acceptable threshold levels. To achieve these goals an IPM program is one which is flexible, incorporating a diverse range of control mechanisms and ' reducing reliance on any single mechanism such as chemical pesticide applications. Given that this is a holistic approach to pest control, the implementation of an IPM program has the direct benefit of reducing the use of chemical pesticides in the maintenance program for the golf course. The implementation of an IPM program requires the disciplined completion of a specific protocol of tasks. The results of each task are synthesized to ensure an integrated approach to decision making. The results of some tasks serve as base data on the characteristics of the site and local pest populations while the results of others serve as feedback concerning the effectiveness of the control program. Regardless of the ultimate application of the information generated, each task is critical to the successful implementation of IPM. Descriptions of the specific tasks, in sequential order, follow. Delineation of the Management Area Turf management areas on a golf course for which an area-specific program must be implemented include greens, tees, fairways, roughs, and turf buffers. Each such area is exposed to different types and levels of use activity, different cultural practices, and different pest susceptibilities. Turf species selection and the appropriate application of cultural and ' mechanical maintenance practices are critical first steps to ensure effective and efficient pest control. Turf selection for each area and area-specific cultural and mechanical maintenance practices are discussed herein under the headings of TURPGRASS SELECTION, CULTURAL MANAGEMENT PROGRAM,AND MECHANICAL MANAGEMENT PRACTICES, respectively. ' Initial Information Gathering The gathering of information on potential pest populations ensures that as the turf becomes established the superintendent has the knowledge and tools necessary to anticipate and address likely pest problems. The background information to be gathered during this task should include: ' PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-7 of 13 I. Identification of likely pest species and information on their specific life cycles and their physical, cultural, and biological requirements. 2. Identification of all applicable controls available for each identified pest species. These controls would include cultural, biological, and chemical options. 3. Information on pest infestations and successful control strategies experienced in the area of the site. There are many potential pests of turfgrasses. Common ones include the fungal species Pythium and Rhizoctonia, the bacteria Xanthamonas, various insects and nematodes, weeds such as nutsedge, and mammals such as shrews, moles, and ground hogs. An initial list of , potential pests at the Peabody Municipal Golf Course is provided below. It must be recognized that this list is not exhaustive. The list is provided solely for the purpose of providing the superintendent with a base for an expanded list to be developed as a site-specific history of pest outbreaks is established. Weeds Fungi/Diseases Insects Small Animals Annual bluegrass Dollar spot Sod webworm Raccoons Crabgrass Snow mold Japanese beetle Ground hog Dandelion Pythium blight White grub Moles Spurge Pythium root rot Ants Shrews Plantain Summer patch Bluegrass billbug Canada geese Clover Brown patch Cutworm White-tail deer Yellow tuft Nematodes Eastern cottontail Necrotic ring spot Hyperodes weevil Chipmunk Typhula blight Sources of initial information include university extension services, local exterminators, local lawn care professionals, and superintendents of other area golf courses. Each of these potential sources should be consulted personally by the course superintendent. Monitoring of Pests and Non-target Organisms Monitoring consists of the frequent examination of each course management area to , determine the status of pest and non-pest organisms. Information to be gathered includes the identification of species present, their level of activity, and extent of impact. Monitoring is essential if the superintendent is to be able to make early and accurate diagnoses of pest 1 presence and threat prior to the pest reaching unacceptable levels. Monitoring for weed, insect, and small animal pests can be done through visual inspection of the turf surface, thatch, and root zones. The intensity of monitoring activities for weed and insect pests should be adjusted to reflect the life cycles of the potential pests. For example, monitoring for specific weed pests should be intensified when the species are most likely to germinate given the time of the growing season and specific environmental conditions , conducive to such germination. While turf will not display symptomatic signs before weed germination, symptoms of moderate insect infestations may be detectable. Accordingly, PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-8 of 13 , monitoring for insect pests should include sample censusing to both establish an action threshold and determine when the threshold is exceeded. Monitoring for early disease and fungal detection is more difficult. Early detection often is ' impossible and the rapidity and severity of damage caused by such diseases as Pythium blight dictate the need for preventative applications of fungicides when and if environmental conditions are favorable for the development of the disease. The incidence of disease has been found to be closely linked to measurable environmental conditions, primarily high temperature and humidity, degree of sun exposure, and leaf wetness. Optimum temperatures for the development of a number of diseases likely to affect the Peabody Municipal Golf Course are as follows. Disease Optimum Temperature Range(°F) Dollar Spot 60 to 85 Snow Mold 68 to 77 Pythium Root Rot 52 to 70 Pythium Blight 74 to 93 Summer Patch 83 to 87 Brown Patch 70 to 90 Yellow Tuft 48 to 75 Necrotic Ring Spot 59 to 82 A number of diagnostic tools have become available in recent years to aid in the early detection of diseases, but their effectiveness remains spotty. These tools range from simple predictor models using readily collected environmental data to diagnostic kits utilizing biochemical information. Examples of the predictor models include those developed for Pythium blight by Nutter et al. (1983). An example of the biochemical diagnostic kits is that developed by Agri-Diagnostic Associates. The Agri-Diagnostics detection kit includes immunoassays for four diseases: Pythium blight, Brown patch, Yellow patch, and Dollar spot. Establishing Damage Thresholds and Action Levels As the objective of IPM is the control of pest populations at acceptable levels, it is crucial that sound efforts be made to establish acceptability thresholds for each pest. The threshold of acceptability will vary for each pest and for each management area of a golf course. For example, greens are expected to support a higher quality turf than rough areas; accordingly, the acceptability threshold for a given pest on a green will be much lower than the threshold for a rough area. The setting of thresholds involves consideration of economics and the tolerance of the golfers. The superintendent will establish appropriate thresholds based on these considerations. Action levels are levels of synthesized information which indicate that damage thresholds are, or are about to be, exceeded. Such synthesized information will include weather and cultural data, the specific period of the pest life cycle, and the accumulated knowledge of previous experiences controlling the pest on the site. Although some guidance on the initial setting of action levels can be obtained, the levels thus established should be set very conservatively and adjusted upward only as site-specific history information has been developed. Initially, the PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-9 of 13 i superintendent should consult with other golf course superintendents in the area to establish action thresholds. Define Effective Treatments The full range of potentially effective treatments for each pest should be identified and , assessed as to its applicability to given situations. This range would include biological, cultural, and chemical treatments. The attached document entitled 1997 Pest Management Recommendations for Commercial Turfgrass by Cornell Cooperative Extension identifies the range of treatment options available for most turfgrass pests encountered in the northeastern United States. Appropriate cultural practices which have the effect of reducing pest infestations to levels below the action level are discussed herein under the heading of CULTURAL MANAGEMENT PROGRAM. The following discussion focuses on biological and chemical control treatments. Biological control is defined as the regulation of pest populations by their natural enemies, including antagonists, parasites, and predators. Biological controls, if target-specific, can be effective. However, frequently this effectiveness is unpredictable. This unpredictability means that the superintendent will be taking a risk in selecting such a treatment that may place the , turf in jeopardy. For this reason a decision to select a biological control must be made early in order to provide an opportunity to implement other strategies. In general, biological control efforts have been targeted to insect pests. Research on biological control of disease and weed problems has only recently begun. One proven effective biological control is the use of the bacteria Bacillus popilliae to produce milky spore disease which, in turn, controls the growth of White grub populations. It has been suggested that predatory nematodes be considered for the control of Japanese beetle grubs and black cutworms. Other biological controllers of insect populations include such small mammals as moles and shrews. These small mammals, however, often cause more damage to the turf than the insects. One effective biological control of a weed pest is the use of corn gluten meal for the control of crabgrass on fairways , and roughs. Chemical pesticide applications are essential elements of any effective IPM program. As with cultural and biological controls, chemical applications should be made only as necessary to preventP acceptable est infestations above table thresholds and only the application if hconstitutes the best available control. Best available control refers to the control effort which will achieve the desired result at acceptable cost and minimum environmental impact relative to other available options. Environmental impact in this context includes damage to non-target species, water quality, and air quality. It is anticipated that a number of currently available pesticides will be used in the maintenance of the Peabody Municipal Golf Course and that yet to be developed pesticides eventually will be used when appropriate. Given the constantly evolving nature of the chemical industry, it is impossible to identify all the chemical pesticides to be employed over the life of the course. At best, a list of currently available and acceptable pesticides may be provided together with a set of operating guidelines for the use of these and future s a list oP roducts. The followingilif P esticides currentlyon the market and registered for use in the control of turf pests. This list is not necessarily exhaustive and must be upgraded as new products which represent best available control are developed. r PEABODY MUNICIPAL GOLF COURSE Turf Management Plan-10 of 13 ' 1 FUNGICIDES Disease Greens/Tees Fatrwa slRou hs Brown Patch chlorothalonil, iprodione, Iprodione mancozeb, PCNB, thiram, triadimefon, vinclozalin.

Use pesticides only as a component of IPM and only to the extent that they represent best available control either singly or in combination with other non-chemical control mechanisms. 2. Use only those pesticides which have been registered for use in the Commonwealth of Massachusetts. 3. Store and apply pesticides in strict conformance with label directions. 4. Use new products as they become available only to the extent that they represent best available control relative to existing products. Making the Treatment Decision The decision-making process is the essence of IPM. Decisions must be made by the superintendent based on the best available data and knowledge of the site gained by site- specific experiences. The goal of all decisions is to utilize the best available control to prevent the exceedence of acceptability thresholds for each turf pest. Evaluation of Treatment and Record-Keeping These tasks provide the feedback information necessary to ensure the selection of best available control over time. The data base established through the completion of these tasks represents the site-specific experience garnered through the implementation of IPM. Each control effort should be followed by a review of the treatments effectiveness and detailed records should be kept in a computerized data base for enhanced retrieval and correlative analysis. Records should specify the location of treatments, the severity of the infestation, the type and level of treatment applied, the date of treatment, and the specific environmental conditions , encountered at the management area immediately prior to, during, and immediately following treatment.

EPA Worker Protection Standard (WPS) for Agricultural Pesticides The Environmental Protection Agency has revised its Worker Protection Standard (WPS) dealing with the protection of agricultural workers from pesticide exposure(40 CFR Part 170). The new Worker , Protection Standard contains requirements designed to reduce the risks of illness or injury resulting from occupational exposures of pesticide handlers and agricultural workers. Accidental exposure of agricultural workers and other persons to pesticides used in the production of agricultural plants on farms, nurseries, greenhouses, and forests are included under these regulations. They include the following: . Restricted-entry intervals (REIs) for most pesticides , . Personal protective equipment (PPE) for handlers and early-entry workers • Decontamination supplies and emergency assistance . Pesticide safety training and posting , . Revised labeling that includes specific WPS instructions For more complete information on reentry and farm worker protection standards, please contact your local Cornell Cooperative Extension office or the Pesticide Management Education Program, Cornell , University, 5123 Comstock Hall, Ithaca, NY 14853, (607) 255-1866. Section 2(ee) Policy , Federal and state laws make it illegal to use a pesticide "in a manner inconsistent with its labeling." Section 2(ee) of the Federal Insecticide, Fungicide, and Rodenticide Act(FIFRA), as amended, defines ' this term and states that certain types of use, although not specifically stated on the pesticide label, are not considered uses inconsistent with the label. These uses, therefore, are acceptable. Under Environmental Protection Agency policy, anyone (including those with a financial in!�:rest in the pesticide) may make a 2(ee) recommendation. All FIFRA Section 2(ee) pesticide recommendations approved by the New York State Department of Environmental Conservation are identified by a number sign (#). All 2(ee) pesticide recommendations approved based on quantitative efficacy data are identified by a double number sign (##). These include recommendations for the following: less than the label dosage; unnamed (not on label) target pests; application methods not prohibited by the label; and pesticide-fertilizer combinations. A copy of , these recommendations must be in the applicators possession when using pesticides under a 2(ee) recommendation. Individual states are allowed to be more restrictive, and New York State has determined that it is ' necessary to place more stringent requirements on 2(ee) recommendations. Under state regulations Part 325.2(b), "registered pesticides may be used only in accordance with label directions or as modified or expanded and approved by the Department." ' Modifications or expansions of registered labels under 2(ee) may be made under the following conditions when used in New York State: tPMR-Commercial Turfgrass- Pestcide Information http://pmep.cce.comell.edu/recommends/turfgrass!pestinfo.html 1.

Once pests are brought under control,a more vigorous turf will more quickly fill the open-spots caused by the pest. Turfgrass varieties and species that are resistant to certain pests, especially diseases, will provide the longest and most reliable control of those pests. When it becomes necessary to use pesticides to control pests,avoid the continual use of one particular pesticide. A dominance of any one pesticide may allow pests to develop resistance to the chemical, and pests that were once unimportant may become increasingly difficult to control. Not all pests are easily controlled by chemicals. The recommended treatments may have to be repeated =� to achieve satisfactory control. Lower rates of systemics, especially herbicides, repeated several times are more effective than an overdose,which could bum the leaves of young growth and thus prevent the movement of the herbicide into the plant. Where a time of application is specified, deviation may cause poor results. Continual use of the same pesticide may encourage the growth of previously unimportant pests. Systemics can be applied in granular form, but the amount of active ingredient may need to be increased over that normally used in a liquid application. For best results, apply systemic granular herbicides and nonsystemic fungicides early in the morning,when there is plenty of dew on the leaves. Systemic fungicides can be applied at an}, time and should be followed by watering or rain. ' Pesticide Compatibility ' Tank mixing of pesticides is allowed if specified on the label or in this bulletin, but precautions are necessary. Each applicator must use the manufacturer's recommended rates and should conduct tests of any specific mixture before using it extensively. Brief guidelines follow: ' 1. Wettable powder formulations usually can be mixed together safely. 2. Never mix emulsifiable concentrates. 3. Insolubles can be tank mixed, provided that products are sprayed at recommended rates. ' 4. Only one soluble chemical can be tank mixed with any number of insolubles. 5. Soluble fertilizers and trace elements can be added, provided that the amount does not exceed I ounce of solid per gallon of tank spray mix. Table 1. Chemical Compatibility, lists the solubility of common turfgrass products for reference in planning tank mixes. Table 1.

Read the label on the container or the specialized turf label for variations in treatment because of season,temperature,moisture, soil type,variety,age of turf, and severity of the problem. The amounts given are for pounds of active ingredient per acre; see the manufacturers label for amounts of formulated material per acre or per 1,000 square feet and for the amount of water to be used with liquids. •1 How to Determine the Amount of Formulated Materials Needed ' Pesticides are usually available in several formulations. In the disease, insect,and weed control tables, you will find the recommended pesticide to use. To determine the amount of pesticide to apply, first note the recommended rate of material based on the active ingredient per area,then note the specific ' formulation of the material you have on hand. Tables 2 and 3 list various formulations in the left-hand column and several rates of active ingredient across the top of the table. Table 2 lists the amount of formulated material to use per acre; Table 3 lists the amount to use per 1,000 square feet. For example: You select oxadiazon 2G to control crabgrass on mature Kentucky bluegrass. The area to be treated is 1,000 square feet. The recommended herbicide rate of active ingredient per acre is 4 lb. Using Table 3, find 2G in the left-hand column. Find 4 lb. of AI/A along the top of the table. Look downward to find that 4 lb.oz. of formulated material will be needed to treat 1,000 square feet at the recommended rate of 4 Ib. AI/A. ' Table 2.

PMEPHome Page J�CemeORuommends 0,1901ilMR C�adrd "'M�'`s'=��.m�fYJ'�vaoi+in¢tddn ' Selection and Application of Turfgrass Fungicides . ' Fungicides used for turfgrass disease control can be categorized as contacts and systemics. Many of the older fungicides are contact fungicides. Some common contact fungicides are listed in Table 5. .� Contact fungicides are typically applied to foliage to prevent pathogenic fungi from infecting leaves. These fungicides are also effective in killing pathogens on thatch and leaf clippings in the turfgrass canopy. Contact fungicides act by killing both dormant spores and dormant and active mycelia of pathogenic fungi. They must be reapplied frequently so newly formed grass tissue remains protected. For contact fungicides to be effective foliar protectants, they must be allowed to dry on the plant surface after application. Therefore, to achieve most effective control of foliar diseases, they should never be watered in or applied in the rain. If they are used to control pathogen activity in thatch, they can be watered in. Because contact fungicides are largely water-insoluble, their movement through thatch is limited and they may not protect roots effectively. Many of the modem fungicides used for turfgrass disease control are systemic fungicides. This means that they move in the plant's vascular system from the original site of application to distant parts. For example, a systemic fungicide applied to turf foliage may move through the plant to protect roots as well as leaves against infection by a pathogen. Most of the systemic fungicides currently used are translocated upward in the plant. A few have limited downward movement as well. The plant translocation of each of various systemic fungicides is given in Table 6. The %%-a% systemic fungicides move in the plant influences the manner in which they should be applied so as to achieve effective control of specific types of diseases. These properties should be considered when developing any disease control strategy that includes systemic fungicides. In general, foliar disease ' control with systemic fungicides is more prolonged when they are drenched into the root zone. For example. foliar applications of upward-moving systemic fungicides provide excellent short-term control of foliar diseases. Drenching the fungicide into the root zone provides a much longer period of protection as well as control against some root and crown diseases. Root disease control with ' upward-moving systemic fungicides is possible only if they are drenched into the root zone, whereas dog+ ward-moving systemic fungicides can control root diseases Ahen applied as a foliar spray. ' Systemic fungicides have the following advantages over contact fungicides: 1. longer residual action, 2. protection of root and crown tissues, 3. suppression of pathogens that have already infected plant tissues, and 4. protection of newly formed plant tissues. ' In addition to the above advantages, many systemics have some contact activity. But systemic fungicides have some disadvantages. Nearly all the systemic fungicides do not actually kill pathogenic fungi but simply suppress pathogen activity. This is usually accomplished through a very specific mode ' of action. Repeated application of one or more fungicides with the same mode of action provides selection pressure that greatly enhances the opportunity for pathogen populations .o become resistant to these fungicides. Once resistance to a particular fungicide develops,that fungicide is no longer effective. Therefore. no one particular fungicide should be used repeatedly over prolonged periods of time. The development of fungicide resistance can be minimized by ' 1. alternating fungicides with different modes of action; 2. using fungicides with different modes of action in mixtures; or 3. alternating or mixing systemic fungicides with contact fungicides to give the desired disease ' control.

Those in different fungicide classes have different modes of action. Therefore, broad-spectrum systemic ' fungicides that control many different turfgrass diseases should always be mixed or alternated between fungicide classes and never Aithin a fungicide class. Likewise, fungicides specific for Pythium diseases should always be mixed or alternated between classes. , Table 5.

Milky (spore) disease, a bacteria that infects Japanese beetle grubs, has been applied extensively on turfgrass in the Northeast for many years but is of questionable value in New York State because (1) the bacteria is most infective to Japanese beetle grubs and is of limited value against other common grub species infesting turfgrass in NYS; (2) soil temperatures in NYS are often too cool for rapid disease buildup: therefore. it often takes several years (minimum) for disease populations to rise to sufficient levels to make an impact on grub populations; (3) milky disease bacteria can only multiply within the living bodies of grubs; thus one must be willing to tolerate a period of relatively high grub populations to obtain disease levels sufficient to control grubs.

Do not use chlorpyrifos if any thatch is present. The use of entomogenous (insect parasitic)nematodes as a control cannot be given unqualified endorsement at this time.Nematodes have provided grub control equal to or ' superior to that of currently labeled turf insecticides,but the number of failures is sufficient to caution their use. Failures have been traced to the use of nematodes in poor physical conditions; the use of nematode strains not well suited for control grubs; and soil conditions that prevent nematodes from surviving, reproducing, or persisting in the field.

The most common causes of turf deterioration that leads to weed encroachment include poor fertility, use of grass species not appropriate.for the site, environmental stress,wear, and damage from insects and diseases. A good cultural program planned around current fertilizer, irrigation, mowing recommendations, and effective insect and disease control is the best defense against weed invasion. Mechanical Removal Mowing newly established turf areas early will eliminate many of the weeds that germinate in the seedbed. On small areas that are not heavily infested with weeds, hand-digging is an effective method of control. Be sure to remove as much of the underground plant parts as possible. Where weeds infest large areas, weed populations are heavy,or creeping or rhizomatous weeds dominate, manual removal is generally not practical. Chemical Weed Control Two basic strategies for chemical weed control are availablepreemergent and postemergent. Preemergent , herbicides control only weeds from seed and generally have little effect on emerged plants; consequently, preemergent herbicides are effective only when applied before seed germination. Postemergent herbicides control weeds after they have emerged. Many herbicides are registered to control weeds in turf. Use the following guidelines to select the most appropriate herbicide for your particular weed problem: . Efficacy on the target weed species �. Will it control the target weed? . Longevity of residual control(if preemergent) How long will the control last? Will multiple treatments be necessary? Will the residual interfere with my overseeding program? • Turfgrass species and management r Will the herbicide injure the turfgrass species on my site? Is it registered for close-cut turf such as tees and greens? • Weed status or growth stage Do I need a preemergent or postemergent product?For a postemergent treatment,does weed age or size (tiller number)affect product or rate selection? ' • Weed control spectrum Will other(incidental but important)weeds also be controlled? For example, crabgrass will be controlled, but what about the spurge or goosegrass that occurs sporadically? .

(Roundup) at the rate required for specific weeds: a normal rate of 2 lb./A or 2 qt./50 gal. water/A (1 1 / 2oz./gal./1,000 sq. ft.) is adequate for grass control. Allow seven days before vertical cutting and seeding. For best results, use a seeder that places seed in the mineral soil under the thatch. Do not contact foliage of desirable plants. This treatment provides no residual weed control. Do not use glyphosate in galvanized or unlined steel sprayers. i 1997 PMR-Commercial Turfgrass-Chemical Weed Control http://pmep.cce.comell.edulrecommends/turfgrass/table8,htrnl Ism Susceptibility of Broadleaf Weeds to Postcrnment I Icrbicides To Top For more information relative to pesticides and their use, 5123 Comstock Hall please contact the PMEP staff at: Cornell University Ithaca,New York 14853-0901 (607)-255-1866 Last Modified: 12/16/1997 Questions regarding the development of this web site should be directed to David Weineart Disclaimer: Please read the pesticide label prior to use.The information contained at this web site is not a substitute ' for a pesticide label.Trade names used herein are for convenience only.No endorsement of products is intended,nor is criticism of unnamed products implied.

The Depart- ment of Environmental Protection(DEP)recommends that applicants submit this form with the Notice of Intent,as well as supporting documentation and plans, to provide.stonnwuter information far conservation commission review. If a particular Stormwater management.standard cannot be met, infonnation should be provided to demonstrate how adequate water quality and water quantity protection will be provided by the project. DEP encourages engineers to use this form to certify that the J project meets the stonnwater management standards as well as acceptable engineering.standards. This farm,should be completed by checking the appropriate boxes for each standard and by signing and stamping the back of this form.
