T' he&Bond Section 2 Existing Conditions The project site is the City-owned McGrath Park, located at 46 Marlborough Road in the City of Salem and identified as Assessors Map 9, Lot 38. A USGS Site Locus and other maps illustrating the site and surrounding area are provided as Figures 1 through 3 in Appendix A. McGrath Park consists of soccer fields, asphalt basketball courts, a playground and associated parking, benches, sheds and utilities in the southwestern areas of the site. The northeastern portions of the site are undeveloped woodlands. During recent sewer work at the McGrath Park athletic fields, fill material was encountered. Because fill material was found, the City proactively contracted Tighe & Bond to analyze the fields. Tighe & Bond proceeded to conduct an extensive soil sampling and testing program of both the upper and lower athletic fields at the Park. Elevated levels of the metals lead, cadmium, nickel and arsenic were discovered in the lower fields. The elevated metals at the McGrath Field are likely associated with fill material from the historic municipal landfill at the site. After the initial testing result, the City took the precautionary measure to close the lower fields until further notice. The upper fields remain open as the soils tested in these fields were determined to be within acceptable limits established by the Massachusetts Contingency Plan (MCP; 310 CMR 40.00000). Photographs of the site are provided in Appendix B. Further assessment of the Park was conducted to determine the limits of fill materials, and to further assess subsurface conditions per the requirements of the Massachusetts Contingency Plan (MCP). This work was conducted with the goal of defining the limits of the old landfill and incorporating a soil barrier with physical upgrades to the Park. Based on the assessment of environmental conditions at the Park, Tighe & Bond has designed a soil barrier over the old burn dump. The City is taking this opportunity to improve the Park by upgrading the field, tot lot playground and parking area. As McGrath Park is an important recreational resource serving the citizens of Salem, the City is working quickly to design and construct these improvements to restore the use of the Park as soon as possible. The City hopes to have the site under construction as soon as late summer or early Fall. The improvements to the Park incorporate the rebuilding of the lower and upper fields, upgrading and increasing the on-site parking, relocating the tot lot playground to the center of the site, upgrading the concession stand, adding bathroom facilities connection to the existing trail. The Park upgrades are focused on better meeting the needs of Salem residents and providing easier access to the Park from the surrounding neighborhoods. Photographs of the site are provided in Appendix B. 2.1 Methodology of Wetland Resource Area Delineations An evaluation of inland wetland resource areas was conducted on May 8, 2011 by Tighe & Bond. Jurisdictional resource areas under the Massachusetts Wetlands Protection Act (MAWPA) and Salem Wetlands Protection and Conservation Ordinance in the vicinity of the proposed work were delineated in accordance with 310 CMR 10.00 and MassDEP guidelines. Bordering Vegetated Wetland (BVW) delineation field data forms are Notice of Intent: McGrath Park Improvements, Salem, MA 2-1 Section 2 Existing Conditions Tighe&Bond ' provided in Appendix B of this Notice of Intent (NOI). The location of each flag was recorded by traditional ground survey. Access restrictions prevented some wetland areas from being identified as definitely jurisdictional or not under the MAWPA or not, when there was no bordering waterbody observable from the property limits. These wetlands which are only potentially jurisdictional under the MAWPA are conservatively treated as BVW in this NOI and on the plans, and noted in the following text. The Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Community Panel Number 250102 0005B (revised: August 5, 1985) was reviewed during the preparation of this NOI to determine the extent of lands subject to flooding. I A copy of the FIRM map is provided in Appendix B. According to this source, the project area is not located within the 100-year flood zone. As such, Bordering Land Subject to Flooding (BLSF) is not present at this location. 2.2 Descriptions of Wetland Resource Areas Wetland resource areas were observed and documented within the proposed project areas including Bordering Vegetated Wetlands (BVW). Resource areas and Buffer Zones thereto are shown on the project drawings. A description of each resource area delineated is provided below by reference id (i.e. alpha-numeric series). 2.2.1 Bordering Vegetated Wetland Wetland resource areas observed and documented within the proposed project areas consist of Bordering Vegetated Wetlands (BVW). Resource areas and Buffer Zones thereto are shown on the project drawings. A description of each resource area delineated by Tighe & Bond on May 8, 2011 is provided below by reference id (i.e. alpha-numeric series). The following flag series delineate freshwater wetlands along the project route. Although a bordering waterbody was not observed at the majority of the following wetland areas due to access restrictions, they are conservatively treated as BVW in this NOI and on the plans based on a review of available mapping (e.g. USGS, MassGIS DEP Wetlands 1:12,000). Site photographs representative of these resource areas are provided in Appendix B. • A and B series Wetland Flagging: Flags A-1 through A-23 and B-1 through B- 28 delineate a forested/shrub swamp wetland located to the west of the Park's main parking lot. Flow from this wetland continues through a culvert underneath Marlborough Road. Typical vegetation identified in this wetland includes black ash (Fraxinus nigra; FACW), boxelder (Acer negundo; FAC+), silky dogwood (Cornus amomum; FACW), and common reed (Phragmites australis; FACW). In some areas within the wetland the microtopography is pit and mound, and/or historically altered. Signs of historical waste deposits were observed in this iwetland. • C series Wetland Flagging: Flags C-1 through C-27 delineate an emergent wetland located to the southeast of the existing basketball court and lower playing field. This wetland is connected to the larger D series wetland outside of the subject parcel and receives flow from a culvert underneath Marlborough Road. Typical vegetation identified in this wetland includes common reed. The Notice of Intent: McGrath Park Improvements, Salem, MA 2-2 I Section 2 Existing Conditions Tighe&Bond wetland extends within an electrical transmission line right-of-way. Signs of past disturbance, rutting, and historical fill were observed. • D series Wetland Flagging: Flags D-1 through D-31 delineate an emergent wetland located to the southeast of the two playing fields. This wetland continues off of the subject parcel and is connected to the C series wetland. Typical vegetation identified in this wetland includes common reed, skunk cabbage (Symplocarpus foetidus; OBL) in the interior, and a small amount of elderberry (Sambucus canadensis; FACW-). The wetland extends within an electrical transmission line right-of-way. Signs of past disturbance and rutting were observed. 2.3 Rare Species The Massachusetts Natural Heritage and Endangered Species Program (NHESP) Atlas, 13th Edition, effective October 1, 2008, and data layer maintained by Massachusetts Geographic Information System (MassGIS), data valid as of April 2011, were consulted during the preparation of this NOI. A map illustrating MassDEP Priority Resources in the vicinity of the project site is provided as Figure 2 in Appendix A. According to these resources the proposed work is not located within mapped Priority Habitat for Rare Species or Estimated Habitat for Rare Wildlife. � i � l � I I I Notice of Intent: McGrath Park Improvements, Salem, MA 2-3 1 I l i 1 s II 1 i _ Var. I J ' Tighe&Bond Section 3 Proposed Conditions The work proposed in the NOI is associated with improvements to McGrath Park, ' including remediation activities under the MCP and improvements to Park amenities as described below. ' Copies of the site plans pertinent to MAWPA and Salem Wetlands and Conservation Ordinance jurisdiction are provided at reduced-scale in Appendix A of this NOI. Full-size copies are provided under separate cover. 3.1 Remediation Remediation activities are proposed . in accordance with the requirements of the Massachusetts Contingency Plan (MCP). As noted previously, assessment activities have been conducted to define the limits of the fill materials under the fields and parking lots. Based on the assessment of environmental conditions at the Park, Tighe & Bond has designed a soil barrier over the old burn dump to protect park users. The soil barrier will be 24 inches deep in the field areas and 6 inches deep under the paved parking areas. A marker layer will be installed under the barrier to define the vertical limits of the impacted material. The marker layer will be a bright material so that the "no dig" ' area is clearly defined in the event someone is excavating in this area in the future. The soil barrier design will be submitted to.MassDEP for review under the MCP process. The goal of the remediation effort is to achieve a "Response Action Outcome" (RAO) with an ' Activity and Use Limitation (AUL) under the MCP. ' 3.2 BVW Improvement During the site investigation, some historical fill material was identified at the surface of wetland series A/B. The City is proposing to remove the materials present at the surface ' within the limits of the BVW, which consist of fiber materials and miscellaneous historic debris. The staging area for this removal will be located in the adjacent upland parking area located immediately to the east of the wetland Series A/B. Heavy equipment, such as an excavator with a bucket or boom and arm will be used to "pick" out and remove ' most of the waste items with minimal impact to the wetland itself. Items will be removed by hand as necessary to further minimize disturbance to the wetland resource area. The waste will then be transferred to trucks for off-site disposal. The removed materials will be hauled to a licensed disposal facility. This remediation effort will result in approximately 2,300 sf of BVW impacts. However, ' construction methods will be employed to minimize impact to soil and vegetation to the maximum extent practicable. In locations were soil within the BVW is disturbed, the area will be raked and seeded with New England Wetmix (wetland seed mix) from New England Wetland Plants, Inc. Seeded areas will be stabilized with a layer of straw mulch ' not to exceed one (1) inch in thickness. 3.3 Park Improvements The improvements to the Park incorporate the rebuilding of the lower and upper fields, upgrading and increasing the on-site parking, relocating the tot lot playground to the center of the site, upgrading the concession stand, adding bathroom facilities and ' Notice of Intent: McGrath Park Improvements, Salem, MA 3-1 Section 3 Proposed Conditions I Tighe&Bond tconnecting to the existing trail. The Park upgrades are focused on better meeting the needs of Salem residents and providing easier access to the Park from the surrounding ' neighborhoods.. 3.4 Construction Period Protective Measures t The following Best Management Practices (BMPs) will be implemented during construction to minimize the potential for erosion and sedimentation of wetland resource areas. 3.4.1 Construction Sequence The final sequence of construction will be determined by the selected contractor. The ' anticipated construction sequence includes the following: • Install sedimentation and erosion controls/protective measures ' • Remove vegetation as required, construct soil barrier, complete site grading • Remove fill materials from BVW Series A/B ' • Restore/improve BVW as necessary • Construct stormwater management improvements ' • Construct basketball court, concession stand, playground • Resod playing fields ' • Complete site paving • Install site landscaping ' • Remove protective measures upon receipt of authorization from the Conservation Commission 3.5 Construction Period Protective Measures ' 3.5.1 Erosion and Sediment Controls Wetland resource areas at the site will be protected by hay bales and silt fence. These protective measures will be placed to restrict the Contractor to the areas necessary to ' conduct the work and will define the limits of work. The locations of these barriers are illustrated on the project drawings provided in Appendix A of this document. Typical details are also provided as part of the project drawings. In addition: ' The Contractor will be required to maintain a reserve supply of haybales and silt fence on-site to make repairs, as necessary. ' Protective measures will be inspected after significant precipitation events and repaired, as necessary. The following general measures will be employed to minimize impacts adjacent to ' resource areas during construction: • Erosion controls will be installed as shown on the plans prior to work adjacent to ' wetland resource areas. Notice of Intent: McGrath Park Improvements, Salem, MA 3-2 ' Section 3 Proposed Conditions Tighe&Bond • Erosion controls will be removed and properly disposed following Conservation Commission authorization. 3.5.2 Dewatering In the event that groundwater is encountered during construction activities, standard ' dewatering measures will be employed for trenches and excavated areas if necessary. No untreated groundwater will be discharged to wetlands or waterbodies. Excess water will be discharged overland in upland areas and allowed to naturally infiltrate in well- drained soils. Filtration sacks or similar devices will be employed at dewatering discharges, if necessary. ' 3.6 Site Stabilization Upon completion of construction activities, disturbed unpaved upland areas will be stabilized with sod or will be loamed and seeded with a native erosion control seed mix. ' Seeded areas will be mulched with a light layer of hay or straw that will not exceed one inch in thickness.

The site is currently developed with two (2) existing soccer fields, a basketball court, tennis court, concession stand and associated parking. There is an existing wetland to the northwest portion of the site and another wetland area to the south. The remaining undeveloped portion of the site is vegetated with trees. ' The town recently determined that the site is located on an old landfill. Environmental testing was completed and it was determined that the site should be raised to provide the proper separation from the landfill materials and the play surfaces. The redevelopment of the site will raise the grade from six (6) inches to two (2) feet. The two (2) soccer fields will be replaced in the same location, the basketball court will be relocated and a new concession/rest room/storage building will be constructed. The existing playground will be relocated adjacent to the new concession stand building. Additional parking is being provided to alleviate the current parking issues on the site The proposed drainage design will direct stormwater runoff to the existing wetland systems. The new system will provide deep sump catch basins, oil/grease hoods and a new proprietary CDS water quality unit to treat runoff. The system will also include an underground detention system to mitigate flows from the site. The proposed redevelopment has been designed as practice to be in conformance with the Massachusetts Stormwater Standards for Redevelopment Projects. Due to the nature of the underlying soils, infiltration has not been provided. ' McGrath Park Overview Salem, Massachusetts i2.0 MASSACHUSETTS STORMWATER MANAGEMENT STANDARDS Stormwater discharges occur as rainfall and snowmelt carry pollutants to the surface and to groundwater. New developments can increase impervious surfaces, which alter natural drainage features, increase peak discharge rates and volumes, and reduce recharge, which maintains wetlands and base flows in stream. Development also results in a corresponding increase in the concentrations and types of pollutant loading, including nutrients, solids and salt. Due to the nature of this project, this site is considered redevelopment under the Stormwater Management Standards. For the redevelopment of previously developed sites, the Stormwater Management Standards must be met to the maximum extent practical. If it is not practical to meet all the standards, new stormwater management systems must be designed to improve existing conditions. The proposed redevelopment will enhance the stormwater quality at this site by adding new catchbasins equipped with deep sumps and hoods, as well as introducing a Proprietary CDS Water Quality Unit to remove pollutants and mitigate flow rates. Standard #1: Untreated Discharges No new stormwater conveyances (e.g. outfalls) may discharge untreated stormwater directly to or cause erosion in wetlands or waters of the Commonwealth. Under the existing conditions, stormwater is discharged from the site at two (2) different locations. The proposed site will mimic the existing conditions and discharge at the same points. There are no new stormwater conveyances as part of the redevelopment of this site. ' Standard #1 is me Standard #2: Peak Rate Control and Flood Prevention Stormwater management systems must be designed so that post-development peak discharge rates do not exceed pre-development peak discharge rates. ' To meet Standard #2, the site discharge was analyzed for the 2, 10, 25 and 100- year storm events. A hydrologic study was performed to demonstrate that the peak rate of runoff for each of these storms was equal to or less than those under ' existing conditions. The stormwater modeling system, HydroCAD 8.0 (HydroCAD 8.0, by HydroCAD Software Solutions, LLC, PO Box 350, Chocorua, New Hampshire 03817) was utilized to predict the peak runoff rates from these storm events. A Type III storm pattern was used in this model. The time of concentration was computed using the TR-55 method, which provides a means of determining the time for an entire watershed to contribute runoff to a specific location via sheet flows, shallow concentrated flows and channel flow. Runoff curve numbers were calculated by estimating the coverage areas and then summing the curve number for the coverage areas as a percent of the entire McGrath Park Massachusetts Stormwater Standards ' Salem, Massachusetts ' watershed. The appendix to this report contains a full description of the time of concentration methodology utilized in this report. ' Drainage structures were sized for the 25-year storm using peak runoff rates generated from HydroCAD. Structure sub-catchments were identified and stormwater flows were routed through the system in general accordance with standard engineering practice. Hydraulics calculations for the drainage structures were analyzed for inlet and outlet control, maximum headwater and discharge ' velocity during the 25-year storm event using the HydroCAD 8.0. Existing Conditions ' The following is a description of the two (2) points of analysis in the existing condition. (See Appendix C for the Pre-Watershed Plan WS-1 and calculations) ' Discharge Point 1 (DPI) Discharge Point 1 (DP1) collects runoff from Pre-Watershed Area 1 (PRE 1). PRE 1 is comprised of the northwestern portion of the site, which includes a portion of the existing building and parking lot. Runoff from this area in collected in an existing drainage system and flows towards the northwest of the site where it discharges directly into an existing wetland. For the purpose of this drainage analysis DP1 is located in this wetland. Discharge Point 2 (DP2) Discharge Point 2 (DP2) collects runoff from Pre-Watershed Area 2 (PRE 2). PRE 2 is comprised of southern and eastern portions of the site, including portions of the existing parking lot, as well as portions of two (2) recreational fields. Runoff from this area sheet flows towards the south of the site where it is discharged into an existing wetland. For the purpose of this drainage analysis DP2 is located in the wetland. Proposed Conditions ' The following is a description of the same two (2) points in the proposed condition. (See Appendix D for the Post-Watershed Plan WS-2 and calculations.) Discharge Point 1 (DPI) Discharge Point 1 (DPI) collects runoff from Post-Watershed Area 1 (POST 1). POST 1 is comprised of new parking, playground and consignment building. Runoff is collected in a new proposed closed drainage system where it is treated with a proposed CDS water quality unit, and mitigated in a proposed underground detention basin. Ultimately runoff is discharged at the same point as in the pre- development condition. ' Discharge Point 2 (DP2) Discharge Point 2 (DP2) collects runoff from a portion of the new parking area as well as the proposed fields. Runoff will mimic the existing conditions by sheet flowing towards the existing wetland. McGrath Park Massachusetts Stormwater Standards ' Salem, Massachusetts 1 � ' Peak Rate Comparisons ` The following table summarizes and compares the pre- and post-development peak runoff rates for the 2, 10, 25 and 100-year storm events.

Standard 2 is me Standard #3: Recharge to Groundwater Loss of annual recharge to ground water shall be eliminated or minimized through the use of infiltration measures, including environmentally sensitive site design, low impact development techniques, best management practices, and good operation and maintenance. At a minimum, the annual recharge from the post-development site shall approximate the annual recharge from the pre-development conditions based on soil type. This Standard is met when the stormwater management system is designed to infiltrate the required recharge volume as determined in accordance with the Massachusetts Stormwater Handbook. Due to the nature of this site, and the known contamination of the old landfill, infiltration is not advisable. Natural infiltration will occur in all pervious areas however, the proposed drainage system has been designed to prevent infiltration into the soils. Standard #3 is met to the maximum extent ractical 1 Standard #4: Removal of 80% TSS Stormwater management systems must be designed to remove 80% of the average annual load (post-development) of Total Suspended Solids (TSS). Redevelopment sites shall meet requirement to the maximum extent practicable. It is the intent of the proposed redevelopment to improve the water quality contributed to the closed drainage system by implementing new BMP's to remove TSS from the runoff to the maximum extent practicable. Currently no treatment is available at this site. The proposed redevelopment will enhance the stormwater McGrath Park Massachusetts Stormwater Standards Salem, Massachusetts ' quality at this site by adding new catchbasins equipped with deep sumps and hoods, as well as introducing a Proprietary CDS Water Quality Unit to remove pollutants in runoff discharging to the northern wetland. The CDS Water Quality Unit has been sized to handle the flow generated from the first one (1) inch of runoff which is considered the first flush for this site. Removal Rates: Deep Sump Catch Basins 25% CDS Unit 70% (See Appendix G) Based on these rates a total of 77.5% of TSS will be removed prior to discharge. See Appendix E for TSS Removal Calculation Worksheet.) Standard #4 is met to the maximum extent practicall ' Standard #5: Land Uses with Higher Potential Pollutant Loads For land uses with higher potential pollutant loads, source control and pollution prevention shall be implemented in accordance with the Massachusetts Stormwater ' Handbook to eliminate or reduce the discharge of stormwater runoff from such land uses to the maximum extend practicable. If through source control and/or pollution prevention, all land uses with higher potential pollutant loads cannot be completely protected from exposure to rain, snow, snow melt and stormwater runoff, the proponent shall use the specific stormwater BMPs determined by the Department to be suitable for such use as provided in the Massachusetts Stormwater Handbook. Stormwater discharges from land uses with higher potential pollutant loads shall also comply with the requirements of the Massachusetts Clean Waters Act, M.G.L.c. 21, §§ 26-53, and the regulations promulgated there under at 314 CMR 3.00, 314 CMR 4.00 and 314 CMR 5.00. A landfill site is considered a Land Use with Higher Potential Pollutant Loads ' (LUHPPL). The purpose of this project is to raise the grade over the existing soils by six (6) inches to two (2) feet which will provide a separator layer from the underlying soils. In addition the proposed redevelopment will enhance the stormwater quality at this site by adding new catchbasins equipped with deep sumps and hoods, as well as introducing a Proprietary CDS Water Quality Unit sized to treat runoff generated from the first one 1 inch of runoff, to remove pollutants. ' Standard #5 is met to the maximum extent practicall Standard #6: Critical Areas Stormwater discharges to a Zone II or interim well protection area of a public well supply and stormwater discharges near any other critical area require the use of specific source control and pollution prevention measures and specific stormwater best management practices determined by the Department to be suitable for managing discharges to such area, as provided in the Massachusetts Stormwater Handbook. A discharge is near a critical area if there is a strong likelihood of a significant impact occurring to said area, taking into account site-specific factors. Stormwater discharges to Outstanding Resource Waters or Special Resource Waters shall be set back from the receiving water and receive the highest and best practical method of treatment.

' Performance Evaluation Back to Pr file CDS Inline Unit ::A product from CONTECH STORMWATER SOLUTIONS INC. :: Performance information: This product was evaluated in at least one third-party study. See MASTEP Evaluation Summary__ MASTEP has reviewed three studies for this technology.A 2009 laboratory study of a CDS model 2015, reported by FB Environmental, ! Produced a MASTEP rating of 2 for SSC removal.This study used OK-110 as the sediment mix,tested performance over 7 flow rates from 9%to 129%of system capacity,and conducted a scour test that found no sediment resuspension at flows of up to 137%of system ! I capacity.The other two studies were assigned a MASTEP rating of 3. A 1997.Florida field study measured performance over 5 storm events, did not specify the CDS model tested,and reported sampling or equipment problems in four of the five events.A 2004 NJCAT laboratory study evaluated a CDS model IIPMSU20_20 6 that had been modified to provide"removal of a very fine gradation of particles".The report states that 1CDS)"will only provide itr high efficiency particle removal efficiency CDS screening product in this market."i.e. (presumably)New Jersey.The reconfigured model tested is sold in NY and NJ. It is not clear how available this model is elsewhere. : Results obtained from this study should not be extrapolated for use in estimating performance of CDS models without the modification used here.

December 2004 Continuous Deflection Separation (CDS) Unit For Sediment Control In Brevard County, Florida January, 2000 ' Date: 12/16/2009 Reviewer: Jerry Schoen ' Rating: 2 Brief rationale for rating: MASTEP rating is based primarily on FB Environmental 2009 laboratory study. This study generally followed NJDEP-recommended laboratory test protocols,with some exceptions:no evidence of a Ouality Assurance Project Plan, little discussion of quality control, higher than recommended particle size distribution, limited range of influent sediment concentration,sediments analyzed by SSC method but not TSS. The Florida field study monitored 5 storm events and encountered sampling/equipment problems in four of them. The NJCAT lab study was conducted on a unit that was specially modified for testing in New Jersey, ' and is now being sold in NJ and NY. Other Comments: FB Environmental Associates study: • OK-110 sediment mix used. This is recommended by Maine DEP, but produces sediments somewhat larger than those recommended by New Jersey DEP. • Sediment analysis conducted with whole sample; essentially SSC method. SSC is generally regarded as more accurate than TSS method, but comparisons with other studies or products that use TSS data are problematic. ' • Full range of flows were tested. • Only one target sediment concentration was tested; average influent SSC was 313 mg/I, slightly outside of recommended 100-300 mg/I range. • Scour test was performed; system produced no scour at flows up to 137% of capacity. NJCAT Study • Expectations of sediment removal performance comparable to this study should be confined to units that contain the sediment weir and a 2400 micron screen. • The study did not include a scour test. • A particularly fine sediment mix (Sil-Col-Sil 106, pre-washed to remove all particles> 100 microns),which makes sediment removal more difficult. Higher removal efficiencies may be obtained if sediment particle size range is larger.

Feed control was achieved through using constant feed peristaltic pumps manufactured by Anko Products, Inc. and a slurry tank that was equipped with a high energy variable speed mixer Model #850 manufactured by Arrow Engineering Company and re-circulating peristaltic pumps to assure the larger(>50-µm) particles would not separate from the mixed solution. Eliminating the need to re-circulate the water was accomplished by adding five(5) 550-gallon (gal) tanks. This, along with the existing storage in the laboratory created 1650-gal of source water and 1650- gal capacity to hold the CDS effluent(Figure 2). The CDS oil baffle was flipped over to behave as a sediment weir. ' Slurry was prepared for each test run. This was done by utilizing the constant feed rate of the peristaltic pumps, coupled with the CDS run flow rate, and batched to hit a 200 milligram per liter(mg/L) sediment loading. The actual feed rate was determined after each run, when the actual CDS flow rate was determined. The volume of water and solids required for each run was determined and measured on a triple beam laboratory scale. The dry material was mixed with approximately two liters of water, in two one- liter sample bottles. These were shaken thoroughly and allowed to hydrate until they were used. Test Procedure Tests were run for incremental flow rates of about 25 gallon per minute (gpm) or 5% of the CDS unit's capacity to 250-gpm, or 50% of the unit's capacity. In addition, runs were carried out at flow rates of approximately 340-gpm and 500-gpm to establish TSS removal efficiencies at or near the unit's treatment operating capacity. - For each flow rate, the pump was set to the approximate flow using a digital magnetic flow meter. Once this was set,the pump was switched off. Water in the effluent side of the CDS unit was pumped to influent storage using a 75-gpm submersible pump. The depth in the effluent tanks was measured and was used later in the volumetric calculations to determine precise flow rates for each test run. 1 1 ' The slurry water was measured out and added to the slurry tank, with two liters reserved for rinsing the sediment concentrate containers. The variable speed mixer was started, the re-circulating pumps were started, the sediment concentrate was added, and the containers rinsed and emptied into the slurry tank. The influent pump and the slurry feed pumps were started simultaneously, along with a stopwatch. The system was operated through 1 & 1/3 active CDS volume turnover before the first 250-milliliter grab sample was taken. The second grab sample was taken at 1 &2/3 turnover,with the final sample taken at J ust beyond 2 complete volume turnovers. The system was shut down, with the stopwatch measuring the total run time. The effluent tanks were allowed to settle for about 20-minutes, the depth measured, and then the water was returned to the influent side of the CDS unit. It is possible that some of the smallest particles may not have settled out during this time and were returned to the influent tanks. if so,the removal efficiencies reported would be conservative. Once this was done, the procedure set out above was repeated until all tests were run. Three grab samples were collected for each run, with exception of the 500-gpm run,where it was only possible to achieve two samples due to the influent pump starting to cavitate toward the point when ' the third sample was to be taken. The samples were packaged and sent overnight to Spectrex Corporation, a certified laboratory, in Redwood City, CA. where the samples were subjected to a particle size analysis. 4. Results Spectrex Corporation subjected the 35 grab samples collected from the 12 test conditions to an extensive particle size analysis to determine the sub-100 micion effluent concentration (mg/L) in each i sample as shown in Table 2. (Spectrex first performed a particle number count in one micron increments and then calculated the mass in each particle size range.). The loading in the slurry tank was selected to achieve a TSS influent concentration of 200 mg/L. Actual influent TSS concentrations were determined at 1 the end of each test run based on the actual recorded, verified flow rate into the CDS unit(Table 2). Influent concentrations varied from 160.4 mg/L to 202.9 mg/L,with an average influent concentration of 184 mg/L. The sub-100 micron particle removal efficiencies for each of the 35 grab samples was calculated from these data and are shown in Table 2 and graphically in Figure 3. Figure 3 shows a wide scatter in the data. This is possibly a consequence of the particle counting ' method deployed especially for the resulting low effluent concentrations. This is not a science that follows a standard method and each provider of this technique has developed and perfected their processes for determining the results. The method is expensive, but was selected due to its ability to accurately discern the particle sizes in the samples in a timely manner. Moreover, as expected,the results indicate a decreasing TSS removal efficiency with increasing operating rate. The deployment of a sediment control baffle in lieu of the oil baffle used in the earlier Portland State University study improved the TSS removal ' efficiency substantially over that verified in the earlier NJCAT verification report. 1 ' 9 Figure 3 - Efficiency of CDS Model PMSU20_20_5 for Sub-100 Micron Particles i 100 — �� > p . • • ' 2 �£, ---9 E e 90 � y c� n. :-.tom$♦dy i. i�;v�� {,: •t � - ry � v ♦ .•, r 4t 80 �` ♦ '}s:'Y tj-':Tr?' eC,'�° ,.q�' b�{ M,tt�.�t, } Poon gv 70 _ t-75 i'l il O � • ♦r ts�� L ��,rA O W 60 }3.�at .S' Ott 't iax c .,;.' • r ` >:. _ ,, --" N .� } 50 � --r--=-r-----I 0 10 20 30 40 50 60 70 80 90 1001 ■ Operating Rate (%) The weighting factors contained in the NJDEP Total Suspended Solids Laboratory Procedures document were applied to the test results to generate the weighted average removal efficiency as shown in Table 3.

This product was manufactured by the US Silica Company' and the materials used for testing originated from the Mill Creek, OK plant. OK-110 is a natural Silica sand product (SG=2.65) consisting of unground sand that has been processed to produce a distribution of particles between 50-um and 200-pm with a d50 of approximately 105-um.

Test Apparatus Removal Efficiency Testing The CDS consists of a swirl concentrator and deflective screen and is shown in Figure 1. During operation, water enters the CDS unit's diversion chamber where the diversion weir guides the flow into the unit's separation chamber and pollutants are removed. All flows up to the system's design capacity enter the separation chamber, while higher flows are bypassed around the separation chamber where they travel through the volute area before discharging through the outlet. Treated water moves through 2400-micron screen aperture openings, under the oil baffle and exits the system. The separation screen remains clog free due to continuous deflection. The CDS2015 used for testing consisted of a 5-fl diameter welded aluminum structure with a maximum depth of 4.17-ft between the floor of the sump and the invert of the unlet pipe.

Arrows indicate flow pathway. (Figure courtesy of Contech Construction Products, Inc.) A peristaltic pump (Randolph Austin) was used to inject slurry into the slurry injection port at a flow rate of 7 gpm to 15 gptu depending on desired sediment loading rate. The pump also served to circulate water through the underlying manifold of the slurry tank before injection so as to eliminate any possibility of sediment accumulation in the manifold. A one-inch, three-way ball valve was used to divert the slurry recirculating through the slurry tank manifold to the injection port via an injection manifold consisting of one-inch wire-reinforced PVC tubing and a vane- indicator flow meter (ERDCO See-Flow. 3222-03T0). Influent samples were collected by reversing the ball valve to recirculate the slurry into a 500 ml sample bottle prior to injection, as seen in Figure 4. Effluent was sampled directly by sweeping a 500-mL sample bottle through the free discharge from the effluent pipe. Effluent from the CDS outlet pipe freely discharged into the catch tank and was pumped back to the influent line after passing through the filter bags. The effluent filter consisted of a plate containing eighteen 7-in dia. x 34-in long, 50-pm nominal-rated, polypropylene felt filter bags. Background samples were collected by dipping a 500 ml bottle into the furthest bay of the catch tank downstream from the filters. The operational procedure for removal efficiency testing consisted of performing multiple runoff simulations (situs). Prior to each sim, a new slurry solution was prepared by filling the drained and cleaned slurry tank with 1200-L of tap water, activating the pump and mixer, and adding the predetermined quantity of OK-110 material. Slurry was allowed to mix and recirculate in the November 5, 2009 5 FB Environmental Associates, Inc o6s��i!1 Once sampling was complete, the flow rate was increased and the sampling process was repeated. This continued until the maximum flow rate was achieved. The operational procedure for re-suspension testing consisted of performing two runoff simulations (sims), one at sediment storage at 50% of capacity, the other at 100%. Each Sim was begun by commencing effluent return flows at a predetermined flow rate. After attaining a steady-state flow condition using clean influent, flow rate and temperature of water in the test apparatus was measured. The system was then given 3 residence times to equilibrate before the fust set of effluent and background samples were taken at 1-min intervals. After each set of six samples, the flow rate was increased and sampling was conducted again. The initial target flow rate was set at 0.1 efs, and increasing through the following series: 0.28, 0.63, 0.88, 1.22, 1.47, 1.76, and 1.92 efs. These flows correspond to the target flows of the removal efficiency testing. Actual measured flow rates are presented in Table 2. Following the collection of the last set of re-suspension samples, flow to the test unit was stopped. The test unit was drained, emptied, inspected, and refilled with OK-110 to the appropriate sediment storage capacity between simulations. Since the invert of the effluent pipe was several feet above the water surface elevation of the catch tank, effluent was sampled directly from the discharge of the effluent pipe. All sampling was conducted in the presence of an observer from FB Environmental. Results and Discussion Removal Efficiency Testing The testing plan was successfully carried out. All 21 test runs were completed, three at each of the seven stated treatment capacities, with results presented in Table 1. The results of the testing were inserted into the weighted NJDEP efficiency calculation assuming a 100%treatment rate of 1.4 cfs yielding a weighted removal efficiency estimate of 70% (Table 3). Measured flow rates were between 0.12 and 1.8 cfs, corresponding to between 9% and 129% of the treatment rate for the CDS 2015 using the weighted New Jersey Department of Environmental Protection (NJDEP) methodology to estimate performance. Influent'concentration averaged 313 mg/L, compared to a target concentration of 300 mg/L. Reported influent and effluent values for each Sim are averages of grab samples taken once per minute for six minutes immediately after the calculated detention time at the appropriate flow rate. Data integrity was very good. Six grab samples were taken of influent, effluent, and background TSS concentrations during each test run, for a total of 126 samples each, and a combined total of 378 grab samples. During the course of sampling, a total of five influent samples were considered outliers. No more than one grab sample per sample run was excluded, and a maximum of 2 out of 18 possible influent samples (over three test runs) were rejected for any given target treatment capacity. Dixon's Q-test was used to confirm outlier status. Removal of these outliers resulted in a more conservative statement of removal efficiency, since their TSS figures were higher than the corrected average influent concentration in every case. Three effluent samples and three background samples were lost during processing (e.g., accidental November 5, 2009 7 FB Environmental Associates, Inc Table 2: Observed re-suspension performance of the CDS Model 2015 using influent with zero TSS, and sediment storage capacity at 50% and 100%of capacity.

As seen in Table 2, at 50% sediment storage capacity, effluent concentration remained at or below the limit of analytical detection (4 mg/L) across the range of flows from 0.09 cfs to 1.92 cfs. At 100% sediment storage capacity, effluent concentration was below the limit of detection for flow of 0.12 cfs to 1.75 efs. Only at 1.91 cfs (corresponding to 136%of the design capacity) was there detectable TSS, averaging 7 mg/L. Background sediment concentrations were below the limit of detection throughout both re-suspension trials and were not used to adjust effluent concentrations.
