RE= Narrative ,for :WPA .Notice" of: Intent is _ for Maynard plastics Co,npany Lot_I .Swampscott Road'„filed •by _ .. :;the Fafard Companies Dear Commissioners The following information is submitted to you as supporting data for the WPA Notice of Intent for the construction of an Industrial Development "Maynard Plastics Company', portions of which will be within the 100 foot buffer zone: and also for the point source discharge from a Storm Detention Basin into the adjacent wetlands. Part 1 Site Description: This lot is located on the south side of Swampscott Road near the Salem/Swampscott Town Line. The lot contains 13.02 acres of land all zoned for Industrial use. I1 is also a portion of the former "King” property which, L5 approx. 42 acres in total area. The majority of the lot (rear 10 acres) is located within a large t watershed about 63.4 acres in size. It is bounded in the north by + Swampscott Road, in the east by Highland Avenue, in the south by a large swamp and ii the west by W.S. Tennis @ Squash Club. The U.S.G.S. Surfical Geology Soils Map shows the general soils to be of the Chattfield/Hollis Association. A detail description being as follows: Chattfield/Hollis Association--' consists of Chattfield and Hollis _ soils and rock outcrops that occur in such intericate patterns on i the landscape, that it is not pratical to separate them at the scale of mapping. Generally these areas consists of about 40 percent - Chattfield soils, 25 percent Hollis soils, 20 percent rock-outcrop and 15 percent other soils. Major limitations are related to depth to bedrock, rockiness and s'ope. • Chattfield Series consists of gently sloping to very steep , moderatelly deep, well drained and somewhat excessively drained soils on bedrock controlled uplands. they formed in glacial till underlain by crystalline bedrock. Chattfield soils have friable loam to sandy loam surface soil , subsoial and substrata with moderate or moderately rapid permeability, depth to bedrock is 20 to 40 inches . in many places Chattfield soils have very stony or extremely stent' surface. Major limitations are related to depth to bedrock and slope. F: Hollis SEries consists of gently sloping to very steep, shallow, ?; somewhat excessively drained soils on bedrockl. controlled uplands. They formed in a thin mantle of glacial till or residuum from local , bedrock. Hollis soils have friable. fine sandy loam surface soil and subsoil with moderate or. moderately rapid .permeability. Depth to - bedrock is 10 to 20 inches. Major limitations ate related to depth to bedrock, rockiness and slope. PART IT Wr)RK DP9CRT0TT0N The -proposed project involves the construction of an 'Industrial _ — - —Complex for the *MAYNARD PLASTICS COMPANY' .To lessen the impact from --- the stormwater runoff from this site a Storm -Detention Basin has been designed using a computer model of .the S.C.S. TR-55/24 hour storm and then routed through an 18 inch pipe culvert from our . detention basin. The following table gives the storm flows to be expected for the design storm at the subject 18 inch culvert: STORM PEAK INFLOW PEAK OUTFLOW MAX. ELEV, 2 YR. 20.6 CFS 13.4 CFS 73.3 FT. 6 YR. 29.1 CFS 16.9 CFS 74.6 FT. t 10 YR. 35.7 CFS 19.1 CFS 75.6 FT. 25 YR: 45.6 CFS :; 22.1 CFS77.0 FT. 50 YR. 51. 1 CFS 23.6 CFS 77.8 FT. j. 100 YR. 57.8 CFS 24.7 CFS 78.7 FT. The pre-developed runoff generated from a 100 year storm fron this site would be 37.3 CFS and our Storm Detention Basin with it's 18 inch pipe culvert outlet will only allow a developed runoff of 24.7 CFS during a 100 Year storm. This represents a 33.8 percent decrease in storm runoff from this after development. You can now see that fron the above chart that the effect of each design'storm is mitigated thereby lessening the potential fof downstream flooding. Staked hay bales and/or a staked siltation screen fence as shown on the plan, Will be used for siltation and erosion control during construction. All slopes will be loamed and seeded during the final phase of construction. POINT SOURCE DISCHARGE: The quality of the water. discharged from this site will be consistent with stormwater runoff from a lightly trafficked roadway. The developed site will be essentially flat, and will need to be salted only under extreme conditions.Minimal amounts of grease and oil due to long term parking will be mitigated within the detention basin before they enter the wetlands. The size, deversity and interspersion of the vegetation in this wetland will serve it 's nateral function of pollution attenuation. In summary this project will. have no. adverse effect on the wetlands. The of is will also protect the, adJacenttwetlandsaduringnconstructon tTh e storm runoPP factually - reducgd due to the Detention Basin) discharged will not adversely " impact the Wetlands or the abbutting properties.The limited use, low density of the surrounding properties and the nature of the vegated wetland Will', mitigate any adverse effects of the 'storm water discharged from this site: IF you should have any questions concerning this project or report, please give me a call. i%OF - m V.

' As stated in the June 2 letter,'seepage is occurring along the culverts and through the crushed stone roadfill To provide immediate relief; 3-6" diameter holes. were cut in the weir to lower water levels.-- To, provide future relief during flood stages, a sealing method is suggested below. Suggested Sealing Method Use a sealing layer as shown on the attached Figure 1C. Impervious material shall be silt, clay or peat and must be held in place by an underlayment of filter fabric. A fabric similar to "Dupont Typar" (attached) should be used to keep the fines from washing into the trap rock. Existing impervious peat and silt in the pond floor should not be disturbed, with sealing required only on the bank and adjacent to the culvert.

Massachusetts 01970 s T April 30, 1986 Mr. Ronald Killian The Fafard Companies 290 Eliot Street Ashland, MA. 01701 Dear Mr. Killian: Per our discussion at a recent Conservation Commission meeting regarding locations of wetlands on Maynard Plastic' s site, the Commission is of the opinion that the revision shown on plan entitled "Site Plan of Land in Salem, MA,. — Maynard Plastics", dated August 21 , 1985, revised April 10, 1986 , which relocates the access road to Maynard Plastics to allow vehicular movement completely around the building, is an acceptable revision. As noted in Dr. Jerome �/arr' s report, dated February 10, 1986, the actual location of the wetland would allow this revision without encroachment on the wetland. This does not preclude, however, the necessity for returni6g to the Commission for site by site review of each remaining building in the Business Park Development, nor does it negate any of the orders set forth .in Order of Conditions #64-120, dated August 22, 1985. If you have any questions-regarding this matter, please feel free to contact Dale Yale at 744-4580. Sincerely yours, 1" Philip D. Moran l\ Chairman `l In" a: Y F, KzA _ ; .

Because our earlier cut and fill calculations wero based on aerial topo information, the actual cut and fill quantities do not balance and will require our lowering the finished floor elevation and all other proposed grades by one foot. Our careful analysis of this change indicates that it will have no significant impact on the Conservation Commission interests. However, your review will be appreciated and, if you agree with our analysis, kindly notify us. Very truly yours, �� ' George M.

THESE INCLUDED 1 . PRESERVING THE LARGE WETLAND ON THE SOUTHERN SIDE OF THE SITE. 2. PROVIDING FOR A CENTRAL RETENTION FACILITY (BASIN NO. !) AND A SMALL RETENTION FACILITY AT THE FRONT OF THE SITE. 3. THE POSSIBILITY OF PROVIDING FOR A PERMANENT POOL OF WATER FOR THE FRONT (BASIN NO. 2) RETENTION FACILITY. 4. DEMONSTRATING THAT ANY DRAINAGE CONTROLS AT THE SITE NOT INCREASE FLOODING CONDITIONS ON ADJACENT PROPERTY. 2 RUNOFF EVALUATION THE SCS METHOD FOR STORM WATER RUNOFF WAS USED TO EVALUATE PREPROJECT AND POSTPROJECT CONDITIONS. A 100 YEAR STORM WAS SELECTED AS THE DESIGN STORM WITH A 10 YEAR STORM SHOWN FOR EVALUATING LESSER FREGUENT EVENTS. THIS METHODLOGY IS SIMILAR TO THAT USED FOR THE EBERSHOFF PROPERTY (2/15/85 SALEM CONCOM) IN EVALUATING THE USE OF EXISTING WETLANDS FOR STORMWATER STORAGE. THE UPSTREAM PORTION OF THE WATERSHED IS CONTROLLED BY A 60 INCH CULVERT PROPOSED IN THE EBERSHOFF DEVELOPMENT JUST TO THE NORTH OF THE SI?E. THE WETLAND PROTECTION ACT REPORT PROVIDED FOR THAT SITE WAS USED TO DETERMINE INFLOWS TO THE SITE. THE CENTRAL RETENTION BASIN CONTROLS WATER RUNOFF FROM AN AREA ON THE SITE OF 5.5 ACRES. THIS AREA IS INCREASED TO 12.4 ACRES WITH THE ADDITION OF RUNOFF FROM BUILDINGS 5,6 AND 7 DIVERTED INTO THE BASIN NO 1 . THE EXISTING CENTRAL BASIN RUNOFF IS MAINTAINED BY STORING 2.6 ACRE FEET OF RUNOFF DURING THE 100 YEAR STORM. EXISTING RUNOFF VALUES FOR LESSER FREGUENT STORMS ARE ALSO MANTAINED PROPORTIONALLY. THE CULVERT UNDER THE MAIN ACCESS ROAD IS DESIGNED TO FUNCTION IN CONCERT WITH THE EBERSHOFF PROJECT AND RETENTION BASIN NO. 1 . RETENTION BASIN NO 2. IS DESIGNED TO MAINTAIN THE 100 YEAR STORM RUNOFF OF 31 .5 CFS. A STORAGE VOLUME OF 70567 CU FT IS NEEDED TO MAIN?AIN THIS FLOW DURING THE 100 YEAR EVENT. THE CULVERT OUTLET IS DESIGNED TO CARRY THE RETENTION BASIN OUTLET PLUS THE DRAINAGE FROM UNDER THE MAIN ACCESS ROAD. SUMMARY TABLES AND CALCULATION SHEETS ARE ATTACHED. THE PROPOSED WORKS ARE SHOWN ON THE PLAN. 3 V - ----- 9 tAi Ha"[Yl ,' C- F�dj oM :� Mu •J 5A C', '-SH, vt Jami Nel Hr,ttf;: h _fim .. ...............

February 10, 1986 prepared for: The Fafard Companies 290 Eliot Street Ashland, Mass. 01721 VIP* prepared by: Carr Research Laboratory, Inc. 17 Waban Street by »� < (�J• [ � — Wellesley, Mass. 02181 Jerome B. Carr, Ph.D. 1. 0 Introduction The Carr Research Laboratory, Inc. has been engaged to review the delineation of bordering vegetated wetland as resource areas under the existing regulations for the Wetlands Protection Act. We were specifically requested to review three areas that had already been mapped and to map some areas where either mapping had not been done, or where previous wetland flags had been lost. All of the areas requiring a review of resource areas were at the rear of the site. A sketch plan of the 5 areas is attached as Figure 1. The project engineers will .be locating the flags as hung in the field and placing that information on a set of detailed plans. Figure 1 herein is just a sketch plan for general discussion purposes. The site was visited on 28 January 1986. The staff for this visit were Jerome B. Carr, Ph.D. Telmatologist (Wetland Scientist) ; and Charolette Cogswell , who is just finishing her Ph.D. thesis in Botany. There was a very light cover of snow on the ground, but not enough to interfere with the wetlands location process. It should be noted by all parties, that the process of mapping the resource area known as bordering vegetated wetlands involves an evaluation of the "vegetated community. " The vegetative community consists of three or more layers of plants, the usual layers being the tree layer, the. shrub layer , and the herb layer. For mapping a vegetative community, biomass doesoft equal vegetative community; thus by breaking the community into three layers, we compare trees with trees, shrubs with shrubs, and herbs with herbs. Then all three layers are given equal weight. This process satisfies the requirements of the wetland regulations and specifically avoids the problem of comparing a tree with a blade of grass. Where there is a question about the exact limit of the bordering vegetated wetland, then we do a complete evaluation of the vegetation around each station. We use a 10 foot radius circle, and where the border is sharp we break the circle into 2 semicircles and evaluate the plants in each semicircle separately. This accents the picture of the wetland border and such stations are referred to as "split stations. " Appendix A contains the station data. All locations flagged in the field are on blue flags with "CRL V on each flag. Other blue flags are present, but they are nor ours. Each of the 5 areas that are the subject of this evaluation are discussed below. 2 .0 Resource Areas 2.1 Area 1 Area 1 is a small finger of low area extending off of a larger wetland area. The question here was, "What type of resource area is this, bordering vegetated wetland or isolated land subject to flooding?" Given that there is a moderately high ridge along the southeastern side of the finger of low area, the answer lies at the neck where the larger wetland joins this low area. In the center of the low area itself, we saw ice and a plant community that would qualify as a bordering vegetated wetland if the area were an integral part of the larger wetland. Since there was no channel connecting this plant community to the larger wet area, then for this small area to be a bordering vegetated wetland, the plant community has to continuously maintain its identity as a bordering vegetated wetland between the two wet areas. -1- Area 1.. North Upland 100 Wetland and Area 2 , l Upland Area 3 Wet- land Upland 1 1 III r Area 4 .- Wetland Wetland with Brook Area 5 ` Upland with Very steep slope. 'K 0 �A 4'd de Figure 1. Sketch Plan, Fafard Co. site, 1I 1 Swampscott Road, Salam, Mass. S� 1 e�'A \ -2- ' 1 To resolve this issue, we carefully documented 4 stations in the low neck between this small low spot and the larger wetland. As seen on pages A-1 and A-2 , at station 1 the upside is dominated by non-resource area plants in all three layers, while on the down side, resource area plants dominate in the tree and herb layers. At station 2 on the upside, both the tree layer and herb layer are dominated by upland plants, while on the downside, all three layers are dominated by resource area plants. On stations 3 and 4 , on the upside the red maples are dominated by non-resource area plants, while on the downside, the wetter areas are clearly dominated by resource area plants. On the basis of the observed plant distributions, it is our best professional judgement that the resource area bordering vegetated wetland is not continuous in this low area and that the low finger is not a bordering vegetated wetland (because it is not bordering) , and thus is only an isolated land subject to flooding. On this basis, the area can be altered as long as flood storage is taken care of. 2.2 Area 2 Area 2 is a larger finger of land protruding from the larger wetland. Here the issue is exactly as above. There is a stone wall cutting across the area, and flag 5 is hung along this stone walla In looking into the lowest area inside the finger of lower land, we determined that because of the shrub layer, if the area was connected to the main wetland, then it would qualify as bordering vegetated wetland. Lacking both a hydrologic connection and a continuous resource area vegetated community, then the land would only be isolated land subject to flooding. In this case, there is a ridge along the stone all, and we - only had to evaluate the plants along the ridge. We used a long thin evaluation area rather than two duplicate circular stations. On page A-3 we see that on the high side of the ridge, the tree layer and the herb layers are totally dominated by non-resource area vegetation. The shrub layer is dominated by resource area plants, but even these are wet-dry tolerant plants. Given that two layers reflect dry conditions, it is our best professional judgement that station 5 is the limit of the resource area known as bordering vegetated wetland, and that the area in the finger could only be considered as isolated land subject to flooding. 2.3 Area 3 Area 3 had a very sharp border and we located a number of old flags along that border. We totally concur with the original border as mapped. 2.4 Area 4 Area 4 is along the north side of the existing brook. The wetland area was dominated by red maples, highbush blueberry, sensitive ferns, sweet pepperbush, and spicebush. Standing water was commonly close to the edge of the wetland. The slope in this area was moderately steep, and upland plans were dominated by black cherry, briers, buckthorn, and lady fern. .Our flag numbers are 6 to 15 . Beyond 15 , the toe of the slope is the wetland border. -3- 2 ,5 Area 5 Area 5 is on the southern bank of the brook. The resource area is pretty much at the toe of the very steep slope which leads to the higher upland. Some resource area trees and shrubs .have crept a short distance up the slopes, or occasional floods have discouraged upland plants in the lowest slope areas. The border is sharp and is easy to map. The resource area plants dominating the wetland are again just as in area 4 , since we are dealing with different banks of the same stream. The upland side was dominated by oaks and black cherry, briers and poison ivy, a few yellow birches, plus lady fern. There are a few other upland species like yew trees, but they are not dominant. 3 .0 Summary Based on the results of our detailed site inspection, areas 1 and 2 can be downgraded from bordering vegetated wetland to isolated land subject to flooding. This is because there is no channel for hydrologic connection, and there is an upland vegetative community separating these areas from the nearby larger wetland. Area 3 has a sharp border, and areas 4 and 5 had their wetland borders located. The borders of these latter two .areas were very close to the toe of the slope of the upland. This is common.

Sincerely, IEP, Inc. /Wc'of'y� Martha S. Snow Geologist MSS/ei BRANCH OFFICES: WORTHINGTON. OHIO BARNSTABLE. MASSACHUSETTS y 4 ICC. 1 .0 INTRODUCTION IEP, Inc. was retained by the Fafard Companies in July, 1985, to test a pile of contaminated soil at a site located southwest of Swampscott Road in Salem, MA. The tests were performed to further characterize the type and extent of contamination. Testing also involved sampling of in situ soils - and groundwater. Results and a copy of this letter have been submitted to DEQE, along with recommendations for remedial action. - 2.0 BACKGROUND INFORMATION The Fafard Companies' 43 acre site, located at 58-96 Swampscott Road in o Salem, MA (please see fig. 1, site locus, and fig. 2, site plan) was vacant, undeveloped wooded property until June, 1985, when the Fafard Companies began clearing the land in preparation for development. In March 1985, IEP, Inc. completed a 21E environmental site assessment for the property. Approximately fifty 55-gallon drums, and thirty or more five-gallon _ containers were found on the property at that time. Most of the drums were very rusted, and their contents could not be visibly identified. A few - barrels contained metal filings and cutting oil . A soil sample collected at four to five feet beneath one of the drums (TP-4) contained 15,183 mg/l oil and grease. IEP, Inc. recommended that additional field work be performed to (1) further characterize the contaminated material and to determine its aereal extent and volume, and (2) to identify the contents of the drums. A remedial design based upon analytical results, and a cost proposal for clean-up -- contractors was to be submitted to the Fafard Companies, and to the DEQE for their approval . IEP, Inc. was not hired at that time to perform such additional field work. Zecco, Inc. , a hazardous materials clean-up contractor of Northborough, MA, was instead hired to remove the drums and contaminated soil on the site. This procedure was begun on June 27, 1985, after Zecco, Inc. had one or two soil samples analyzed for EP Toxicity and oil and grease content. The Fafard Companies .hired IEP on June 20, 1985 to be present on the site to supervise the clean-up. IEP was also asked to contact the DEQE to inform _ them of the removal , and to request that a DEQE official be present on site. Approximately 728 cubic yards were excavated on June 27, 28 and 31 by Zecco, Inc. and transported to Narragansett Improvements in Rhode Island. Because only a limited sampling program had been completed, the only criteria used for determining contaminated vs. uncontaminated material was visual - discoloration and, occasionally, odor. The volume of contaminated material excavated and left on site was approximately 600-700 cubic yards. Because - the lateral extent of contaminated material was greater than anticipated, costs incurred by the Fafard Companies were also much greater than had been EIG%URE 1 : SITE LOCUS 58-96 SWAMPSCOTT ROAD (43 acres) SALEM, MA.

IEP, Inc. suggested that the excavation be stopped, and the pile of material be further characterized to determine if some other remedial action might be appropriate. 3.0 SAMPLING _ Sampling was initially performed by IEP in March 1985 for a Chapter 21E environmental site assessment. Two soil samples analyzed at that time for - oil and grease content contained 15,183 mg/l and 2,067 mg/l oil and grease (Arnold Greene Testing Laboratories of Natick, MA) . A surface water sample collected from the nearby swamp for heavy metals analysis contained slightly elevated cadmium and lead levels. o After Zecco, Inc. removed approximately 730 cu. yds. of material , IEP began a sampling program of (1) the waste pile, (2) the remaining in situ soils and (3) the groundwater. The following is a description of that sampling program. 3.1 Waste Pile Sampling Program On July 12, 1985, two composite soil samples were collected from the waste .__ pile to determine the approximate oil and grease contaminant level , and two composite soil samples were collected to determine if any PCB's were present in the soil . Laboratory data sheets are contained in Appendix B. On August 1, 1985, a random sampling program was performed on the waste pile. Eight soil samples were collected for oil and grease, PCB, and volatile organic content (Four by ASTM, four by EPA Method # 624) . Three samples were collected for EP Toxicity analysis. Specifics of sampling methods and handling are presented in Appendix A, and laboratory data sheets in Appendix B. 3.2 In Situ Soil Sampling Program On July 26, 1985, three test pits were excavated at the perimeter of the area where the contaminated material had been removed. See Figure 2, Site _ Plan for their locations. Test pits one and three were excavated to a depth of approximately six feet, and test pit two to a depth of 8.5 feet. Test pit two was extended into a 30-foot long trench. Three samples collected from test pit one were analyzed for oil and grease, PCB and volatile organic content, respectively. " Four composite soil samples collected along test pit two (Trench) were analyzed for oil and grease, PCB volatile organics content, and for EP Toxicity, respectively. L i:.`. 1T , c A composite soil sample was collected from test pits two and three for a hydrocarbon fingerprint. (Results - Appendix B. ) 3.3 Groundwater Sampling Program On July 26, screened 5 foot by 2 inch PVC pipes were installed through the -_ water table in each of the three test pits excavated. Screens in test pits two and three were screw-coupled to a five-foot riser pipe. On August 1, observation wells in test pits two and three were purged and allowed to recover. A large puddle surrounding the screen in test pit one made purging and sampling of the groundwater there impossible. Water samples were collected from,,test pits two and three for volatile organics analyses. 4.0 ANALYTICAL RESULTS All but the following samples collected on July 12, 25, and August 1, 1985, _ were submitted to Resource Analysts, Inc. of Hampton, NH: (1) July 25: Two oil and grease samples collected from test pits one and two, and one fingerprint sample collected from test pits two and three, and -- (2) August 1: All eight oil and grease samples collected from the waste pile. These samples were submitted .to Arnold Greene Testing Laboratories of Natick, MA. See Appendix B - Laboratory Data Sheets. The following is a � . summary of the laboratory results for each of the sampling programs outlined in Sections 3.0 - 3.3 above. 1_ 4.1 Waste Pile Laboratory Results July 12 sampling: The two composite oil and grease soil samples collected contained 2900 ug/g (ppm) (0.29%) and <80 ug/g (ppm) oil and grease. One of the two composite PCB soil samples contained 2.7 ug/g (ppm) PCB - 1260. No PCB's were detected in the second PCB composite sample. August 1 random sampling: Laboratory results for EP Toxicity analyses are presented below in Table 1. Oil and grease and PCB results are summarized in Table 2. Volatile organics results (analyzed by EPA Method # 624) are summarized in Table 3. Oil and grease and volatile organics results (Analyzed by ASTM Method) are presented as laboratory data sheets in - Appendix B. All other laboratory results were obtained verbally from Laurie Clark of R.A.I. , and will be included in Appendix B as written lab reports upon receipt at IEP. r-- 4.2 In Situ Soil Laboratory Results July 26 sampling: No volatile organic compounds or PCB's were detected in the composite soil samples analyzed for those constituents (Two samples for PCB, two for VOA) . The results of the EP Toxicity test for metals were far below the maximum allowable concentrations under the EP Toxicity test. Oil and Grease results were 2,152 mg/Kg (ppm) and 2,017 mg/Kg (ppm) for -- samples from test pits one and two, respectively. A "fingerprint" or determination of the type of petroleum contamination present in the soil suggested the presence of No.6 fuel oil . Environmental degradation of the material made it difficult to obtain an unambiguous identification. (See Appendix B.) 4.3 Groundwater Laboratory Results August 1 sampling: No volatile organics were detected in a water sample obtained from test pit observation well 2. A water sample obtained from -- test pit observation well three contained 250 ug/1 (ppb) of methylene chloride. 5.0 DISCUSSION There are three areas of concern at the site: the waste pile, in situ soils, and groundwater. It is IEP's opinion that none of the contaminants detected are present in high enough concentrations that disposal of the material off-site is required. I- 5. 1 Waste Pile The PCB's in the waste pile, while present at concentrations up to 12.4 ug/g (ppm) , have a mean of 3.9 ug/g (ppm) for the whole waste pile. DEQE officials in the Woburn, MA office have stated that the maximum contaminant f- level allowable on a site is 50 ppm (under the Federal Toxic Substance Control Act, TOSCA) . Material with concentrations above this level must be �- disposed of at an approved landfill . A level of 10 ppm has been used by the State as a preferred guideline or background level that PCB-contaminated I ` sites must be cleaned up to. The mean level of 3.9 ppm is well below the -° State's 10 ppm guideline, and the TOSCA regulation level of 50 ppm. Oil and grease concentrations from the waste pile range between 0.22% and 0.57%. One fingerprint analysis of a composite sample taken from test pits two and three (not the waste pile) indicated the presence of a highly weathered No.6 fuel oil , although the weathered nature of the material precluded definitive identification. Volatile organic analyses of the soil by the ASTM Method D 3871-79 (GC/FID) , conducted for screening purposes, detected low levels of toluene, carbon C tetrachloride, 1,1,1-trichloroethane and three other compounds, all below 9.0 ppb. Analysis by the EPA Method 624 (GC/MS) revealed low levels (less than 2.6 ppb) of volatile organic compounds; primarily benzene, ethyl benzene and xylenes. The EPA Method 624 for volatile organics analysis is a more definitive analytical method and should be used over the ASTM Method. Results of the EP Toxicity for metals analyses are far below the maximum acceptable levels for the EP Toxicity test. L_ 6.0 SUMMARY AND RECOMMENDATIONS _{ Groundwater dowmgradient of the site is not used as a municipal or private drinking water supply. The nearby North Shore Tennis and Squash Club does have a private water well installed in bedrock. Depth of this well is not known, but it is not directly downgradient of the site. The Salem Transfer Station, built on an old landfill , is approximately 1/4 mile directly upgradient of the site. It is not known what impact, if any, the transfer station and landfill have on the site. However, the Fafard Co. plans to I extend Salem's municipal water main from the transfer station south along Swampscott Road to the site. Future groundwater usage at the site is Ltherefore not anticipated. The DEQE has in the past employed the guideline that oil -contaminated sediments with oil and grease concentrations less than 1% can remain on site J if the oil is clean oil , not waste oil . The origin of the oil at this site is not clear; however, the extensive analytical work done to characterize it indicates the following: 1) low mean PCB of 3.9 ppm 2) soil is well within acceptable EP Toxicity levels 3) minimal volatile organic contamination 4) one fingerprint analysis indicates a highly weathered No. 6 fuel oil . L The oil appears to be relatively free of contaminants which might be found in waste oil , and does not fall within the State's 10 ppm guideline for PCB's or under the Federal TOSCA regulatory 50 ppm for PCB's. IEP therefore recommends that the clean oil guidelines be applied to the contaminated soil C at this site. Remedial action for the waste pile should consist of aeration r and ultimate disposal on-site. Table 1.

Results in Appendix B. -mss APPENDIX A Random Sampling Method Sampling stations' SS-1 through SS-8, used to determine where oil and grease, PCB, and volatile organics samples were to be taken in the waste pile, were located using a random sampling procedure. EP Toxicity samples were taken 4 at three random locations in the pile, chosen from among the eight. An 3'- eighty-foot long baseline was extended the length of the approximate middle of the area of the waste pile. The baseline was divided into four segments of 20-foot length. A random numbers selection was then used to determine two transect lopi along each segment (I to 20 feet) . Another random numbers selection was then used to determine the transect loci that were to extend at a right angles from the baseline at each locus. The pile is yapproximately 50 feet wide, so the transects crossing the pile were chosen — from numbers 1 to 25 (feet) . A right-left, right-left sequence was chosen for determining which side of the pile the cross transect was to be performed. At each sampling location, a composite sample was taken through the pile to the underlying polyethylene liner. The thickness of the pile varied from five to six feet at the start of the baseline (1 to 20 feet) to six inches - to two feet at the 60 to 80 foot end of the baseline. One liter clear glass jars with teflon liners were used for oil and grease i'=-- analyses, 500 ml amber jars and 250 ml amber jars, both with teflon liners, were used for PCB and volatile organics analyses, respectively. EP Toxicity anaylses were collected in 500 ml amber jars with teflon liners. All samples were chilled overnight at the IEP, Inc. laboratory and shipped to either Resource Analysts, Inc. or Arnold Greene Laboratories for analysis on August 2, 1985. u•4 ss-g ss- C 8o, ss-7 C sz-3 58-5 13S'1 L' - Appendix B LABORATORY DATA SHEETS -- o i i_ L I i C C L C RAI Resource Analysts, Incorporated Box 4778 Hampton, NH 03842 (603) 926-7777 TO: PO # Job # Fafar-6 I Date Received: 7-12-85 (4:35) Ms. Martha Snow IEP, Inc.

Enclosed please find four (4) copies of the Maynard Plastic's "As-Built" plan, dated May 14, 1986. David Westerling, P.E. , has prepared a letter certifying that the project has been completed in accordance with the existing Order of Conditions. His letter will be delivered to Dale Yale before the June 26 meeting. Enclosed also is Mr. Westerling's June 21 Engineering Report on Improvements To Detention Pond, Mavnard Plastics. Finally, a letter from Maynard Plastics agreeing to the conditions set forth in the Order of Conditions will be received by Dale Yale prior to the June 24 meeting. On behalf of Maynard Plastics and The Fafard Companies, I respectfully request the Salem Conservation Commission to approve a Certificate of Compliance for this project at its June 26 meeting.

As stated in the June 2 letter, seepage is occurring along the culverts and through the crushed stone roadfill. To provide immediate relief, 3-6" diameter holes were cut in the weir to lower water levels. To :provide future relief during flood stages, a sealing method is suggested below. Suggested Sealing Method Use a sealing layer as shown on the attached Figure 1C. Impervious material shall be silt, clay or peat and must be held in place by an underlayment of filter fabric. A fabric similar to "Dupont Typar" (attached) should be used to keep the fines from washing into the trap rock.

Per our discussion at a recent Conservation Commission meeting regarding locations of wetlands on Maynard Plastic' s site, the Commission is of the opinion that the revision shown on plan entitled "Site Plan of Land in Salem, MA. - Maynard Plastics", dated August 21 , 1985, revised April 10, 1986, which relocates the access-road to Maynard Plastics to allow vehicular movement completely around the building, is an acceptable revision. As noted in Dr. Jerome Carr's report, dated - .February 10, 1986, the actual location of the wetland would allow this revision without encroachment on the wetland. This does not preclude, however, the necessity for returning to the Commission for site by site review of each remaining building in the Business Park Development, nor does it negate any of the orders set forth in Order of Conditions #64-120, dated August 22, 1985.

The Conservation Commission would respectfully request that you address these issues in order for us to properly evaluate the site. I look forward to hearing from you as soon as is convenient . Sin ryrely yours, Dale E. Yale - Staff Advisor cc: George Seeley 28 August, 1985 Mrs. Dale Yale Salem Conservation Commission One Salem Green Salem, MA 01970 Dear Dale, I have reviewed the report by IEP prepared for the Fafard Com- panies relative to the proposed Maynard Plastics site at 58-96 Swampscott Road. I have two comments about this report. 1. Section 3.0 refers to surface water samples that "contained slightly elevated cadmium and lead levels", _T is relative statement needs to be clarified by including the levels of cadmium and lead found in the water sample, and the appropriate water quality standards. 2. Section 5.1 refers to an average PCB content of 3.9 ug/g with a high value of 12.4 ug/g in the waste pile as sampled on 1 August. Table 2 reports PCR concentrations from the waste pile sampled on 1 August in units of mg/g. The laboratory sheets for this sampling are not included in Appendix B as explained in Section 4 .1. The difference of several orders of magnitude between the text and Table 2 needs to be explained to evaluate the PCB content of the waste pile. If the correct units are mg/g, this indicates severe contamination of the waste pile with PCB. Appendix B should include the lab data sheets as soon as possible. I hope the above issues can be quickly resloved. ncerely, Paul Geoghegan - -- - ------ J -'; �� -- --------- - - - - - - - --P-� •--- -__ - - --- - -- ---- -- __� _ _ _ _ -- -- _ _ _ _____ --- --�'- - - - - do - -_ - -. - - - r FIGURE 2 : SITE PLAN j; 58-96 SWAMPSCOTT ROAD SALEM, MA.
