The sediment testing was conducted in response to special condition #7 of the Salem Conservation Commission Order of Conditions issued on July 9, 1992 . There were concerns over contaminants in the sediments near the existing outfall, located off Haste Rock in Salem Sound. The sediment testing was required before construction of a multi-port diffuser outfall that would be 54 inches in diameter and extend 660 ft. (northeast) out from the existing outfall terminus. The new outfall is designed for effluent from the secondary treatment plant now under construction. Four bcrings were made by a contractor on September 12 , 1992 to a depth of eight feet. Fine grain sediments ("surficial black deposits") were found at the surface, followed by dense brown sand deposits. Bedrock was found below the sand and mud, roughly between 10-20 ft. down near the existing outfall and deeper along the track of the proposed outfall. All four borings showed elevated metals (chromium, copper, lead, mercury and zinc) in the surficial black deposits, but all were classified as Category I with the exception of two borings which had Category II chromium levels. The Massachusetts Division of Water Pollution Control considers Category I levels to be clean, and Category II may be subject to disposal restrictions. One boring with high chromium also had elevated levels of polyaromatic hydrocarbons, and therefore would probably not pass testing for open water disposal. The borings showed the dense brown sand deposits were all clean. To summarize, there appears to be some metals in the surface mud that have accumulated from shoreside sources over the years. The origin of the PAH measurement is uncertain. Are these contaminants a concern? Probably not for this project. The contaminants levels are not very high and only 580 cubic yards of If sediments will be disturbed. The path for the new outfall terminus will be cleared using a "screed" to sidecast sediments. The displaced sediments will settle around the new trench (2 ft. deep and 11.5 ft wide) that will house the pipe. Given the small volume of sediment to be moved and relatively low levels of contaminants, the impacts from disturbing the sediments should be minor and short term.

Sodium hypochlorite is the sodium salt of hypochlorous acid used as a bleach, disinfectant, germicide, and deodorizer. It is applied as a solution to the wastewater treatment plant effluent for disinfection at a rate of approximately 4-8 mg/L, and is also used in the odor control scrubber systems. Solutions of sodium hypochlorite vary in strength from 5.25 percent by weight (household chlorox bleach) to 12 to 15 percent by weight (industrial strength). Typically, a 15 percent strength sodium hypochlorite solution (85 percent water) is used in wastewater treatment plant applications. A solution of 15 percent hypochlorite has approximately 1.2 pounds of available chlorine in ea ch gallon. As a solution, sodium hypochlorite is corrosive to skin and mucous membranes, however the solution is infinitely soluable in cold water and can be diluted rapidly upon exposure. When working with this material, protective equipment such as rubber gloves, aprons boots and safe�Ly glasses are recommended. Respiratory protection is not required. Sodium hypochlorite can be dangerous when heated or if placed in contact with acid or acid fumes. Upon decomposition by heat or chemical reaction chlorine gas is released. The sodium hypochlorite used on-site is currently, and will continue to be, stored and used in a manner to avoid such decomposition. Sodium hypochlorite will be stored in a cool area, away from sunlight inside a chemical building in cross linked polyethylene bulk storage tanks. Each chemical storage tank will be surrounded by a concrete berm sized to contain the entire volume stored in the event of a tank failure. In the event of a chemical spill, the sodium hypochlorite will be contained and pumped to an available storage tank or diluted and discharged into the treatment plant. Under no conditions would sodium hypochlorite be introduced to the resource area. CAMP DRESSER & McKEE INC. March 3, 1993 Salem Conservation Commission Page 2 It should be noted that the District has been using sodium hoypochlorite on-site at the Fort Avenue site for over 15 years without incident. Use of sodium hypochlorite for disinfection is expected to decrease with secondary treatment since effluent quality will improve. Other large wastewater treatment facilities using sodium hypochlorite for disinfection include New York City, Chicago, and locally Nashua and Manchester New Hampshire, the Greater Lawrence Sanitary District and the MWRA. Sodium hypochlorite has become more attractive as a disinfectant in recent years since it is considered far less hazardous than chlorine gas. It appears as though your concerns stem from information regarding the use of chlorine gas as a disinfectant. The District evaluated the use of chlorine gas as an alternate to sodium hypochlorite but this was dismissed due to safety concerns even though it was a more economical choice for disinfection. Please contact me if you have any additional concerns or comments. Very truly yours, CA DRESSER & McKEE INC. i Jane E. Madden, P.E. cc: J. Darling R. Masak CAMP DRESSER & McKEE INC. DESIGN MEMORANDUM From: Alan Geronilla RE: SESD Outfall Pre-Design Results of Sediment Quality Program DATE: November 10, 1992 REVISED: December 16, 1992 BACKGROUND The South Essex Sewerage District outfall has been operational since 1926. Between 1926 and 1978, raw sewage was discharged through the outfall. In 1978, primary wastewater treatment came on-line; and, in 1984, sludge discharges were stopped. Currently, the addition of secondary treatment to the wastewater treatment process is being designed. Another proposed improvement to the wastewater treatment plant is the installa- tion of (multiport diffuser that.will connect;to,the:existing,outfall.termmus and extend 200J [meters ,(660#eet) ui the northeasterly direchonl The diffuser may be(placed'on the seabe o (bined,in'a cut and=cover excavatro . Figure 1 presents the locus of the site. The objective of the sediment quality program is to characterize the physical and chemical constituents of the sediments underlying the proposed diffuser. The recommended con- struction:technique for the installation of this diffuser will involve the use of a screed' The screed process will�tly"sidecast';;the"surficial sediments, so that the diffuser and pipe bedding may be placed upon the relatively denser native sands that lay underneath the surficial sediments. The sediment quality program involved the collection and analysis offcore"samples_up toJa �deptli'of 8'feet, which corresponds to the maximum potential dredge depth the diffuser V ould be buried. If burial, over the use of a screed, was selected as the preferred construc- tion technique, the data from this program could be used to evaluate the feasibility of dredge sediment disposal at either the Massachusetts Bay Disposal Site or an upland loca- tion. Four environmental borings were drilled during this program, the locations of which are presented in Figure 2. The sampling and analytical procedures followed regulatory proto- cols established by the U.S. Environmental Protection Agency (EPA), the U.S. Army Corps of Engineers (ACOE), and the Massachusetts Department of Environmental Protection (MDEP). These procedures, approved by the three agencies and by the Massachusetts Coast- al Zone Management Office (MCZM), were presented in a sampling and analysis plan submitted on August 28, 1992.

APPLICABLE REGULATIONS FOR SEDIMENT CHARACTERIZATION 314 CMR 9.00: Certificates for Dredging, Dredged Material Disposal and Filling in Waters. These MDEP Division of Water Pollution Control regulations pertain to the characteriza- tion of sediments relative to dredging methods, disposal methods, and placement. Both the chemical and physical characteristics of the sediments are ranked/categorized by these sediments. The sediments are ranked Category 1, 2, or 3 based on their chemical constitu- ents, with Ctateggy-1 materials being generally Cclean' andi,Category'2 materials being generally polluted.'i+ Under these same regulations, the sediments are ranked Types,B,orb [G based on-physical characteristics. Combinations of the chemical and physical characteris- tics of the sediments identify the allowed/approvable methods of dredging, disposal, and placement of the sediments. (See Appendix A for relevant ranking criteria.) 310 CMR 32.00: Regulations for the Land Application of Sludge and SeRL=.

T�e 1992 proposed changes to the regulatory criteriaaerrfected-therein._, SAMPLE COLLECTION PROCEDURES Sampling of the sediments was conducted on September 17, 1992.1 These environmental samples were collected by vibrato coring to a depth of eight feet below the seabed. The vibratory coring method involved pneumatically driving a 4-inch diameter core barrel into the subsurface. Within the core barrels were Lexan tubes, which were capped and stored on ice upon collection of the 8-foot sample cores. The sampling locations were determined with a microwave positioning system, at the following coordinates (presented in State Plane, NAD 1983, coordinates): Boring ID East North OF-5 778,717 560,388 OF-5A 778,740 560,436 OF-6 778,797 560,622 OF-7 779,044 560,914 The sample cores were extruded the following day on the shore, to minimize the possibility of on-site contamination. Upon extrusion, the soils in each sample core were separated according to visible soil horizons, placed in soil jars, stored in ice, and transported to the laboratory for physical/chemical measurements. gackgro nd seawater-samples were taken on the same day that the sediment cores were extruded. The samples were collected approximately 300 feet upstream of the effluent discharge - -3- f , CAMP DRESSER & McKEE INC. GEOLOGY At these four boring locations, the detected soil horizons (with very general descriptions) were as follows: OF-5 0.0 to 3.0 ft Black fine-to-coarse sand, trace silt. 5.5 ft Refusal. Rock (possible debris from original construction) at bottom of core. OF-SA 0.0 to 2.2 ft Fine black sand, with little silt. 2.2 to 8.4 ft Brown fine-to-coarse sand. OF-6 0.0 to 9.0 ft Brown fine sand, with little silt. No surficial black sand. OF-7 0.0 to 1.2 ft Fine black sand, with little silt. 1.2 to 7.2 ft Brown coarse-grained sand, with gravel. In addition to these environmental borings, a geophysical survey was conducted in April 1992 by Ocean Surveys, Inc., of Old Saybrook, Connecticut. The-geophysical sur ey identi- fied bedrock to be'5 to 10 feet 15616,the seabed`in the first 200->&o stage of the proposed diffuser, dropping from 10 feet to 20 feet deep in the succeeding 100-foot stage, and greater than 20 feet deep thereafter. Further, a geotechnical drilling program was conducted on August 20 and 21, 1992 by Haley & Aldrich, of Bedford, New Hampshire. Five geotechnical borings were drilled to 25 feet below the seabed. The locations of these borings (OF-1, OF-2, OF-2A, OF-3, and OF-4) are shown in Figure 2, at the following State Plane, NAD 1983, coordinates. Boring ID E= North OF-1 778,704 560,404 OF-2 778,796 560,653 OF-2A 778,786 560,633 OF-3 778,917 560,781 OF-4 779,052 560,935 Four basic strata were identified in the geotechnical and environmental sampling programs: surficial black sand, dense brown sand, glacial till, and bedrock. The surficial soils at the site comprise coarse- to fine-grained black sand; some of the surficial samples contained a trace of organic silt and/or gravel. The average thickness of the surficial black sand deposits is 2 feet. Near the existing outfall terminus the underlying strata is glacial till. Elsewhere along the alignment, a dense brown sand with trace components of coarser- sands, silt and/or gravel underlies the surficial sediments. At boring location OF-6, the sample core appeared to be homogenous, comprising only the dense brown sands, with no visible surficial black sand layer at the surface. At OF-1, the glacial outwash deposits (till) and bedrock were encountered at depths of 2 feet and 13 feet below the seabed, respectively. [ACOF-5,, refusal was encounte�e&5.5'feet below fhe`seabed" Neither bedrock nor till was detected in the other boring locations. At these locations near the existing outfall, the boring information generally matches the depth of -4- CAMP DRESSER & McKEE INC. bedrock estimated by the geophysical survey. Farther from the outfall, it appears that the actual depths to bedrock are at least 5 feet below those depths estimated by the geophysical survey. Based on the information presented above, a generalized cross-sectional view of the site geology was constructed, and is presented in Figure 3. The estimated locations of the till layer and bedrock are shown therein, as well as the maximum potential dredge depth of 8 feet below seabed.

The'hfghest`coiuentrationsMof chemical constituents were measured at OF-5A-1? The sec=' I nd highest sediment chemical concentrations were measured atfOF-7-1? These two sedi- ment samples are ranked,Category 2;based on 314 CMR 9:00 because of chromium concentra- tions between`100 and 200,pgm. Category 2 sediments are materials that have elevated concentrations of bulk contaminants, at levels often considered sufficient for concern. Surficial sediment samples OF-6-1 and OF-5-1 are ranked Category 1, or generally "clean' materials. At boring location OF-6, no visible layer of surficial black sediments was noted; sample OF-6-1, submitted for chemical analyses, was taken to be the top three feet of the core at that location. The chemical constituents of this sample were measured at Category 1 levels. OF-5-1, closest to the existing outfall, similarly was ranked Category 1. This is in contrast to sample OF-5A-1, which recorded the highest concentrations of most chemical constituents. These data suggest the possibility that the site of the proposed diffuser is not very deposition- al. A review of the historical sediment quality measurements also supports this likelihood, and suggests a substantial abatement of the surficial deposits' chemical concentrations over time, particularly the chromium concentrations. PAHs. The origin of the PAHs detected at OF-5A-1 cannot be explained at this time. Only one historical sample in the general vicinity of the proposed diffuser alignment was ana- lyzed for PAHs (at SS01, in 1987),and total PAHs were detected at a concentration of 93.76 ppm. Because this detection of PAHs at OF-5A-1 represents only the second time that PAHs were measured and detected, no time trend evaluation is possible. Contributing to this ambiguity is the fact that PAHs in the sludge have recently been mea- sured to be around or below 1 ppm. Not knowing what the PAH concentrations had been in the historical sludge, the information is insufficient with regard to identifying the origin of the detected PAHs at OF-5A-1 and SS-01 (in 1987). TBP. The Theoretical Bioaccumulation Potential (TBP) is a guideline for gauging the capa- bility of the dredge material to pass biological testing for disposal at an open ocean site; this is defined in EPA's 1991 testing manual for Evaluation of Dredged Material Proposed for Ocean Disposal by the equation: 4 x Concentration of Nonpolar Organic Chemical divided by %Total Organic Carbon x Organism Lipid Content (4 x CS +%TOC x %L). The TBP of the dredge sediment is compared with the TBP of the reference material at the open ocean disposal site. A lower TBP for the dredge sediment than for the reference material is a positive indicator of the likelihood of passing the biological test that allows disposal of dredge material at the open ocean site. In this discussion, the organic chemical constituent`of:concer_n, CS, is taken to be;PAHs',and, the open ocean disposal site is taken to be the Massachusetts Bay Disposal Site (MBDS). At the MBDS reference site, the total PAHs and %TOC measurements are known to be 1.09 ppm and 2.11%, respectively (provided by Ms. Kymberiee Keckler, U.S. EPA). The ratio C5+ %TOC of the reference material thus is 51.7. At OF-5A-1, the average concentrations of total -9- f CAMP DRESSER & McKEE INC. PAHs and %TOC are known to be 36.4 ppm and .00678%, respectively. The ratio CS+%TOC for the surficial sediment sample at OF-5A-1 thus is calculated to be 5,370. For this one particular sample, therefore,-it is unlikely that.the material will be capable of passing biological testing (EPA/ACOE Tier -III protocols) for.disposal at the MBDS;although it should be noted that PAHs were detected only at OF-5A-1, and were non-detectable at other surficial sediment locations. t-TCLP Testing Samples whose bulk metal concentrations exceeded 20-times the regulatory limit for RCRA- defined hazardous waste were selected for Toxicity Characteristic Leaching Procedure (TCLP) testing. fTwo surficial sediment samples,,OF-5A=1,and OF-7-1,_exceeded this criterion )(d (for chro_miurm*.However, TCLP testing was conducted only for OF-7-1 because no sample I4uje volume remained for OF-5A-1. TTGGOLL..SS'''� The chromium TECLP�testing result for OF-7-1 ,was non-detectable at a detection limit of 0.100 ppm. For comparison, the regulatory limit (stated in 40 CFR Part 128) for chromium is 5.0 ppm. QA/QC SAMPLES One sample each of a rinsate blank and field blank were taken as part of the quality assur- ance/quality control (QA/QC) procedures of this program, as were conducting duplicate analyses of one sediment sample and triplicate analyses of three aqueous samples. Sample Blanks Some chemical constituents were detected in the rinsate blank and field blank, as tabulated below. Constituent Blank Measurement Det ction Limit RINSATE BLANK Boron 0.077 ppm 0.020 ppm Copper 0.015 0.010 Zinc 0.090 0.006 FIELD BLANK Molybdenum 0.042 0.020 Zinc 0.006 0.006 While these detections of chemical constituents in the blank samples suggest the possibility of some cross-contamination in the sampling techniques, because the levels of detection are -10- CAMP DRESSER & McKEE INC. small, it is not felt that the findings and recommendations of the study are invalidated or dependent upon the detection of these chemical constituents in the blank samples. Duplicate/Triplicate Analyses A sediment duplicate was analyzed for OF-5A-1, and aqueous triplicates were analyzed for the background seawater and elutriates of sample OF-5A-1. The analytical results of the duplicate and triplicate analyses generally agree. ELUTRIATE TESTING Elutriate testing was conducted for six sediment samples, with the elutriates of OF-5A-1 analyzed in triplicate. The elutriate test identifies the constituents of the effluent arising from dewatering of the dredged sediments. These constituent measurements then are compared with relevant water quality criteria to determine if the effluent will require pretreatment before discharge into the ocean. The relevant water quality criteria selected for this comparison was the Marine Chronic Criteria. Both filtered and unfiltered elutriate samples were analyzed, and compared to the Marine Chronic Criteria. The filtered elutriate testing results provide some understanding of the dissolved portions of the chemical constituents (i.e., those fractions that would not be removed by filtration alone), and the unfiltered elutriate testing results provide some understanding of the total--dissolved plus particulate--fractions of the chemical constitu- ents. The background seawater was collected away from the existing outfall, and was ana- lyzed, without filtration, in triplicate. The results of the elutriate testing are presented in Table 3. A comparison of the test results with the Marine Chronic Criteria shows that some unfiltered elutriate samples would not pass the Marine Chronic Criteria, whereas all filtered elutriate samples (except one of the OF-5A-1 triplicates) would be capable of meeting the criteria. This suggests that most of the sediments' chemical constituents are adsorbed by the soil particles, and not readily available in the dissolved fraction.

Disposal Method Sidecasting Category 1 materials only Off-site (pipeline or barge) Category 1 or 2 materials Placement: Beach replenishment, in-harbor disposal, or sandy site open ocean disposal Category 1 materials only Conditional land or in-harbor disposal with bulkheading Category 1 or 2 materials Both the surficial black deposits (except around location OF-5A-1) and the dense brown sand deposits appear capable of passing testing criteria for disposal at either the MBDS or an upland location. The upland disposal site location may be any one of certified lined sanitary landfills that satisfy the requirements for disposal of dredge sediments. Based on 310 CMR 32.00, all tested sediments are ranked Type I, and are approvable for direct land application, including daily cover, in a sanitary landfill. Except for the one sample at OF-5A-1, it is very likely that the patchy surficial sediments at the site will be capable of passing regulatory criteria for ocean disposal: either sidecasting or disposal at the MBDS. LIt appears, therefore, that the recommended construction technique,,;,; voly" the use of a screedyis viable for,the placement of the diffuser. The screed would gently push aside or "sidecast" the surficial sediments,Concurrently laying the bedding stone. Assuming a screed depth of 2 feet and a width of about-11:5 feet through the approximately 660-foot length of thepoposed'diffuser,(only about 580 cubic yards of surficial sands would be pushed aside by the screedThese "displaced" sands then would bea ecovered by armor'rocks and ballast rocks that would be used to overlay and protect the diffuser:pipe., NOVEMBER 18, 1992 PRE-APPLICATION MEETING On November 18, 1992, at the suggestion of the ACOE, a Pre-application Meeting was held. The objectives of this meeting were to present the findings of the predesign phase of the project and to solicit guidance from the regulatory agencies regarding the conceptual design and proposed approach to the construction of the outfall diffuser. Invited to the meeting were representatives from the ACOE, EPA, MDEP, MCZM, National Marine and Fisheries Service (NMFS), U.S. Fish and Wildlife Service (USFWS), Massachusetts Division of Marine Fisheries (MDMF), SESD, and CDM. Representatives from MCZM and NMFS were unable to attend the meeting. Following presentation of the project predesign phase results (including this sediment quality program), CDM described the proposed use of a screed for pushing aside the surficial black sands. In the light of the regulatory agencies',assessment that this diffuser project unlikely will cause major environmental impacts, and no objection was,raised on the use of"a screed. Additionally, the removal and reuse of the fill from the existing outfall ' structure was recommended by the meeting participants. o - 13 - APPENDIX A 314 CMR 9.00 CATEGORIZATION CRITERIA (3) Table I Classification of Dredge or Fill Material By Chemical Constituents All units are in parts per million Category One Category Two Category Three Arsenic (As) < 10 t0 20 ) 10 5 5 - 10 ChromiumCadmium 300 >4 (Cf) 100 - 00 Copper (Cu) 200 - 400 )400 <200 Lead (Ph) <100 10U 5 _ 200 >200-5 Mercury (11g) < 0.5 Nickel (NO < 50 50 - 100 >100 Polychlorinated 1.0 ) 1.0 Vnada (PCB) < 75 5 0.75 5 - 125 >125 Vanadiumum (V)Zinc (Zn) <200 200 - 400 >400 those Category One materials are is contain first en�Cels listed in Table I m in coneentrana exceeding those thefir Cateaory Two mater!# are those which contain any one or more of the chemicals lsten in Table 1 in the concentration range shown in the second rblunin.

Ten Cambridge Center ' Cambridge, Massachusetts 02142 Attention: Ms. Bernadette H. Kolb, P.E. t Subject: Pre-Design Phase Geotechnical Engineering Study SESD - Proposed Outfall/Diffuser Salem, Massachusetts Gentlemen: ' This letter report presents the results of subsurface explorations and laboratory soil testing, and documents geotechnical engineering recommendations for the proposed diffuser extension of the SESD Wastewater Treatment Plant Outfall. These recommendations were discussed with you at ' a 5 October 1992 meeting. This work has been performed in accordance with our contract dated 3 March 1992. tPROPOSED CONSTRUCTION It is our understanding that the proposed outfall/diffuser,-(O/D),will consist of a_54-in`:_diameter (pipe`'approximately 660 ft.'injength. The O/D is to extend from the existing outfall outlet ' structure located in Salem Sound east of Great Haste Island (see Figure 1). Two'O/D.optiohs are presently being considered by Camp Dresser & McKee Inc. (CDM): a buried diffuser with ' riseis]extending above the seabed floor, and a shed diffuse) with twin ports equally space along the O/D length. Thegpe of pipe to be utilized has not been finalized at this time. ' EXISTING CONDITIONS The proposed O/D will be located'if ;approximately 27 ft. of water (MLW). The ocean bottom ' along the proposed alignment appears to be relatively flat and slopes downward to the west at an approximately 1.5 percent slope. ' The existing outfall has been in use since the 1920s; initially for raw wastewater discharge and, since 1978, as the outfall for the SESD primary treatment plant at Fort Avenue in Salem, Massachusetts. The existing outfall outlet.structure is located approximately 1.4 miles east of Pine Tree Place 360 Route 101, Suite 801 Bedford, NH 03110 603/472-2054 Branch Offices Cambridge,Massachusetts Glastonbury,Connecticut Scarborough,Maine ' Affiliate H&A of New York Rochester,New York Camp Dresser & McKee Inc. 4 December 1992 Page 2 Salem Neck in approximately 27 ft. of water (MLW). Based on a review of design plans for the existing outfall, it appears that approximately 6 ft. of rock was removed to construct the existing ' outfall terminus The existing outfall consists of a.liuned 54-4ri._diameYer.cast iron pipe supported 49n'8 in.-sq. wood sills spacedat 6 ft intervals. SUBSURFACE EXPLORATIONS Ocean Surveys, Inc. (OSI) of Old Saybrook, Connecticut completed a geophysical survey of a 600 x 900 ft. area located immediately beyond the existing outfall terminus during the period of 23 through 27 April 1992. The survey included the acquisition of hydrographic side-scan sonar, sub- bottom and magnetic data. Locations of the geophysical lines are depicted on Figure 1 (Subsurface Exploration Location Plan and Profile), together with ocean bottom contours developed from the geophysical data by OSI. ' Pre-design phase subsurface explorations conducted by Haley & Aldrich, Inc. (H&A) during 20 and 21 August 1992 consisted of four test borings designated as OF-1 through OF-4 (see Figure 1). The borings were drilled by Warren George, Inc., of Jersey City, New Jersey utilizing a 40 ft. t x 90 ft. jack-up barge. The borings ranged in depth from 23.2 to 25 ft. below the ocean bottom (mud line). Approximately 10 ft. of rock was cored in Boring OF-1. Rock was not encountered in any of the other borings. Standard Penetration Tests (SPT) were conducted continuously in ' the top 10 ft. of the overburden soils and subsequently at 5 ft. intervals by driving a 1-3/8 in. I.D. split spoon sampler with a 140 lb. weight falling freely 30 in. ' The pre-design phase test borings were monitored by a H&A geologist. Logs of the test borings, prepared by H&A, are included as Appendix A. Locations of the borings were determined by Geophysics GPR International, Inc. (GPR), Salem, Massachusetts and are shown on Figure 1. ' Elevations of the ocean bottom (mud line) at the boring locations were determined by GPR utilizing the bottom surface contour information provided by OSI. Elevations in this report are in feet and are referenced to South Essex Sewerage District (SESD) datum, unless otherwise noted, for which El. 0.0 is 4.46 ft. below the National Geodetic Vertical Datum (NGVD). LABORATORY TESTING A soil testing program including grain size distribution/hydrometer analyses, water content and soil resistivity was undertaken at the H&A laboratory. Results of these tests are included as Appendix B. In addition, chemical testing was performed on four soil samples and one water sample by Enesco Co. Inc., of Cambridge, MA to determine potential corrosivity of these materials. Testing included pH, sulfate content, chloride content and sodium content. Results of the tests are included in Appendix B. 2 ' Camp Dresser & McKee Inc. 4 December 1992 Page 3 ' SUBSURFACE CONDITIONS ' Borings conducted in the early 1920s during design/construction of the existing outfall appear to have encountered primarily silt and clay overlying bedrock along approximately 6,000 ft. of the alignment from the shore line. Sand overlying bedrock appears to have been encountered along ' the remaining 2,250 ft. of the alignment to the outfall terminus. Three sub-bottom profiles were developed as part of the geophysical work conducted by OSI in April 1992. The bedrock surface was interpreted by OSI to be typically 5 to 20 ft. below the ocean bottom (mud line) in the southwestern portion of the study area. The interpreted bedrock surface also appears to be about 9 ft. below the ocean bottom at a point approximately 160 ft. from the existing outfall terminus measured along the proposed O/D alignment. The interpreted tbedrock surface dips downward from this point in a northeast direction. Pre-design boring OF-1 is located approximately 40 ft. from the existing outlet structure and encountered glacial till overlying bedrock. The glacial till, approximately 11 ft. in thickness, consisted of very dense, brown,gravelly coarse to fine SAND, little silt. The bedrock is described as hard to very hard, slightly weathered, coarse to medium grained DIORITE. The remaining pre-design borings OF-2, OF-3 and OF-4 encountered medium dense to very dense, brown silty fine SAND, with trace to little amounts of coarse to medium sand and gravel. The borings were terminated in this deposit. ' Borings OF-1, OF-2, OF-3 and OF-4 encountered a 1.0 to 2.0 ft. thick surface stratum of bottom sediments consisting of very loose to medium dense, black coarse to fine SAND, trace organic silt ' and varying amounts of gravel. Figure 1 contains a subsurface profile along the proposed O/D alignment summarizing the test boring results. ' GEOTECHNICAL ENGINEERING EVALUATION General ' A design vertical alignment for the proposed O/D has not been established at this time. CDM has requested that H&A evaluate and comment on geotechnical considerations associated with ' two alternative vertical pipe alignments (fully buried diffuser and surface diffuser). Further, we understand that bottom sediments at existing mud line may be contaminated, and it may be necessary to support a surface diffuser in a manner which does not remove or minimizes disturbance to these sediments. Laboratory chemical testing of the bottom sediments has been ' conducted by CDM. 3 ' Camp Dresser & McKee Inc. 4 December 1992 Page 4 Subsurface soil conditions encountered in the pre-design test borings are generally considered suitable to support either a fully buried or surface diffuser, with the exception of the thin layer of ' bottom sediments encountered at the mud line. If removal or displacement of these sediments is not permitted, then structural support of the O/D pipe, use of flexible pipe or reinforcement/stabilization of these materials will be required. Bedrock excavation should be anticipated in the vicinity of the existing outlet structure, if a fully buried diffuser alignment is selected. Geotechnical design recommendations and construction considerations for the alternative vertical ' pipe alignments are summarized in Table I and are discussed hereinafter. ' 1. (Dune—d Diffuser*1 It is our understanding that the existing 54-in. diameter outfall was constructed as a buried ' structure. The proposed O/D extension could be constructed at the vertical alignment of the existing outfall, as conceptually shown on Figure 2. If this scheme is adopted, it should be expected that in the existing terminus area and to some distance between the terminus and test ' boring OF-1, bedrock will be encountered, and thusCrock excavation will.be required. Depending on the design invert elevation, drilling and blasting may be required to remove rock, since the bedrock consists of competent diorite (an igneous rock). ' The trench for the O/D pipe can be dredged with mechanically operating grapple dredge (clamshell) and dragline equipment. The grapple dredge will work best in the soft and/or loose ' underwater deposits. The sloping sides of an excavated trench in the described soils are expected to be stable at a 1 V (vertical):2.5 H (horizontal) inclination. A bedding layer, consisting of gravelly sand, should be placed at the base of the trench to provide direct support of the diffuser ' pipe. The excavated material may be used as backfill. Armor protection should be included within the backfill zone, if determined necessary by CDM. This design would require excavation and disposal of the mud line bottom sediments. ' II. (Surface-Diffuser tThe proposed O/D section can be designed as a surface structure, as conceptually shown on Figure 3. The thin layer of bottom sediments is not suitable for direct support of the O/D pipe because of its very low shear strength and very high compressibility. Depending on regulatory constraints relative to the removal and disposal of the bottom sediments, the following options might be considered for bedding preparation as indicated on Figure 3: A. Place bedding material, pipe and armor protection directly on mud line::Due 0 impression of the bottom sediments under the applied load, 2 to 3-in. of post--a construction settlement should be anticipated._ ' � b 4 1 1 Camp Dresser & McKee Inc. 4 December 1992 Page 5 1 Consideration might be given to substitute a more flexible'pipe;systemifor rigid reinforced concrete pipe, to tolerate expected joint se tlements. B. Utilize a custom-built screed to facilitate an approximately 10 ft wide strip along 1 C. _ 1 PP Y P g the proposed alignment by displacing (i.e., pushing to the side) the bottom 1 sediments and simultaneously backfilling the displaced zone with gravelly sand bedding material. This procedure is Leexpected to-control t potential postn construction`settlements to about 1t0 inch or,less. 1 C. Place a hea%geotextile (e.g., Mirafi 600X or Tensar geogrid) directly on the mud line. Place the bedding material on the geotextile. It is expected that the geotextile will serve as horizontal (tensile) reinforcement and thus control 1 (potential',post-construction settlement to about Vin.or less'*'—*, Geotextiles have been successfully deployed in the marine environment on other 1 projects. Typically, the geotextile is rolled off the back of a barge while divers anchor ttie?geotextile to the mud line with sand bags. 1 D. If removal of the bottom sediments is not restricted by regulatory requirements, [excavatcthe bottom;sediments. Place the bedding material on the exposed subgrade of glacial till or marine deposits. It is expected that this procedure will 1 limit post-construction settlements to 1/2 in or less. E. If disturbance of the bottom sediments is not permitted by regulatory 1 requirements, and several inches of post-construction settlement are not acceptable,(—pile support may be considered using screw anchors which would sustain both compression and tension. Spacing of the screw anchor bents will 1 depend on the magnitude of the net vertical load, as well as the type of the pipe material. The pipe would be connected to the piles by special fasteners (straps) provided by the screw anchor supplier. Post-construction settlement is expected to 1 be insignificant. Potential difficulties in advancing the screw anchors into the very dense glacial till and dense=very dense marine deposits should be evaluated more closely if this alternative is to be implemented. 1 CORROSIVITY TESTS 1 Results of the chemical tests and electrical resistivity measurements were evaluated relative to potential ambient effects on the proposed outfall diffuser structure, assuming it will consist of reinforced concrete and steel elements. 1 Chemical attack on concrete is generally the result of exposure to sulfates and/or acids. Seawater has a high sulfate content in general and is moderately aggressive to concrete- Water soluble 1 sulfate in soil specimens was determined to range from 0.0711 to 0.0947 percent by dry weight. ( �io h 5 ke h4 ✓, 1 1 Camp Dresser & McKee Inc. 4 December 1992 Page 6 1 This corresponds to "mild" exposure. However, a sulfate content of 2,470 ppm was determined in one water (aqueous) sample, which corresponds to "severe" exposure (ACI Manual of Concrete 1 Practice, Part I, 1991.) Test results for pH range from 7.4 to 8.3 for soil samples, and 7.7 for the water sample, indicating a relatively non-acidic environment. 1 Electrical resistivity values measured in laboratory-constituted soil specimens range from 1,868 to 8,110 ohm-cm at natural water content, and from 1,305 to 6,193 ohm-cm at full saturation. Soils with an electrical resistivity under 1,000 ohm-cm provide easy electrolytic paths for the flow of current from anodic to cathodic local areas on a buried structure (AISI Handbook of Corrosion 1 Protection for Steel Structures, 1981). Based on the test.results discussed above, it is recommended that Type V cement be considered 1 at a maximum water-cement ratio of 0.45 for the concrete mix, if a RC pipe is selected for the project. If a suitable pozzolana such as fly ash is added to the mix in the amount of 15 to 25 percent, most Type II cements would also be suitable. A water-cement ratio of 0.40 to 0.45 is 1 generally recommended to provide adequate resistance to corrosion for the reinforcing steel. It has been a pleasure to assist you on this phase of the project. We trust that the information 1 contained herein will be sufficient for your present needs. Please do not hesitate to contact us, if you have any questions or need further information. 1 Sincerely yours, HALEY & ALDRICH,INC. Richard J.

Gulf of Maine Research Center Inc. of Salem, Massachusetts, evaluated environmental information regarding Massachusetts Wetland Resource Areas at this Site in accordance with ' the Massachusetts Wetlands Protection Act (M.G.L. c. 131, 5. 40) and Regulations ( 310 CMR 10.00) , as well as any applicable local Wetlands ' Bylaws. Proposed activities will result in no significant impact on the Coastal Wetland Resource Areas at the Site. The proposed ' activities will be carried out in a manner such that the performance ' standards of the Massachusetts Wetlands Protection Act (M.G.L. c. 131, S. 40) and Regulations ( 310 CMR 10. 00) are complied with. 1 1 1 ' GULF OF MAINE RESEARCH CENTER INC. ' 1.0 INTRODUCTION This report provides information regarding proposed ocean ' bottom substrate investigations in and adjacent to, Massachusetts Wetland Resource Areas near the existing South Essex Sewerage ' District (SESD) outfall in Salem Sound (the Site - Figure 1) . Only one Massachusetts Wetlands Resource Area has been identified in the 1 area of the proposed activity: Land Under the Ocean (Nearshore Area) . ' The Gulf of Maine Research Center Inc. identified the Coastal Wetland Resource Areas at the Site and served as the environmental ' consultant for the project. Camp Dresser & McKee, Inc. of Cambridge, Massachusetts is the Project Engineer and is responsible for the tSubstrate Investigation. The Substrate Investigation at the Site will be carried out in such a manner as to protect the Massachusetts Wetland Resource Areas according to the Massachusetts Wetlands Protection Act (M.G.L. c. 131, s.40) (hereinafter the "Act" ) and Regulations ( 310 CMR 10.00) (hereinafter the "Regulations" ) . This ' report describes the existing protectable Wetland Resource Areas at ' the Site, and discusses measures to protect the interests identified in the Massachusetts Wetlands Protection Act and Regulations. 2.0 SITE DESCRIPTION ' The location of the proposed activity (the Site) is 1 . 4 miles ' offshore of Salem Neck ( 4203210911N and 70050113"W) within the corporate boundaries of Salem at a depth of 30 feet below mean low ' water. The Site is located to the east of Great Haste Island. Sediments in the location of the proposed activity are present to tdepths of up to 20 feet, although there are areas where the bedrock ' extends to within 5-7 feet of the sediment surface (CDM, 1986) . ' 2 ' GULF OF MAINE RESEARCH CENTER INC. The area around the existing outfall has been subjected to tsewage discharges since the construction of the outfall in 1926 . ' Increased levels of treatment, primary treatment in 1978 and the termination of sludge discharge in 1984, have resulted in improved ' water quality. The waters near the existing outfall are classified SB by the Massachusetts department of Environmental Protection ( 310 CMR 4. 00) . The District' s primary effluent discharge meets the ' standards for SB waters (e.g. minimum dissolved oxygen of 5 . 0 mg/1) . There is excellent circulation in Salem Sound, primarily tidal ' influence. The freshwater discharges to Salem Sound (e.g. the Danvers River) have little influence on current within the sound, but ' can depress salinity during periods of high flow. Summertime ' stratification in the sound, however, is largely thermally controlled. The discharge of treated effluent contributes to the high level ' of nutrients (nitrogen at the existing outfall site. These nutrient stimulate the growth of algal. Thus, algal biomass (measured as ' chlorophyll-a) levels are higher in Salem Sound than in Massachusetts ' Bay. This is a common characteristic of most coastal marine environments, and results from natural and human-related discharges ' of nutrients to coastal waters and coastal upwelling phenomena. The data indicate that the highest single sample of algal biomass in ' Salem Sound is one-half of the lowest level that might be considered ' a nuisance bloom; most samples were much lower. Heavy metals, particularly chromium, are present at elevated levels in the sediments around the existing outfall. The presence of chromium in the sediments at the location of the SESD outfall is ' attributed to its heavy historic use in the local tanning industry ( Ibid, 1986) . ' 3 ' GULF OF MAINE RESEARCH CENTER INC. ' Since the elimination of sludge discharges in 1984 , the benthic community in the vicinity of the outfall has become more diverse. ' Although marine organisms in Salem Sound including mussels and winter flounder have exhibited bioaccumulation of contaminants, recent ' studies show that the outfall is not currently a major contributors to bioaccumulation (CDM, 1991) . 1 The marine resources in Salem Sound include shellfish. As ' defined in 310 CMR 10.34 (Land Containing Shellfish) , the significant shellfish resources in the sound include the soft-shell clam (Mya ' arenaria) , the blue mussel (Mytilus edulis) , and the sea scallop (Placopecten magellanicus) . The extent of known clam and scallop beds is shown in Figure 2 (Figure 3-21 taken from Volume V of the ' Phase II Facilities Plan for Wastewater Treatment and Disposal) . All of these resources are located at a distance of at least three-quarters of a mile (about 4,000 feet) from the area where sediment samples will be collected. With the exception of Devereaux ' Beach in Marblehead, the harvesting of clams and oysters does not ' occur because the beds are gully closed due to coliform contamination. Commercial scallop harvesting is not restricted at I ' this time; scallops are also collected by recreations divers. t 4 ' GULF OF MAINE RESEARCH CENTER INC. ' 3.0 PROPOSED ACTIVITIES ' The South Essex Sewerage District, seeks an Order of Conditions to conduct a geotechnical and physical-chemical investigation of the ' marine substrate in the vicinity of the existing sewerage outfall ' near Haste Rock in Salem Sound. This investigation will require the deployment of a drilling barge at the Site for approximately one to ' ten days of drilling. Soil and rock samples will be obtained at four ( 4) locations within a 660 foot linear distance from the end of the ' existing outfall. The samples will be collected along a line trending northeast from the outfall terminus. These substrate 1 samples will extend to a depth of 20 feet. Rock coring will be ' utilized as necessary to obtain twenty ( 20) feet of penetration for the geotechnical study. ' The area of investigation will be marked by buoys in locations designated by Camp Dresser & McKee, Inc. prior to the deployment of ' the barge. The drilling rig, set on the deck of the barge will be ' tethered in place during the investigation with four stablizing anchors. Because of the temporary nature of the anchorage, work will ' only occur in fair weather; work will be suspended during rough seas. ' Casing will be installed from the platform of the barge to the ' seabed surface and will be advanced as penetration advances with the rotary bit. Disturbed sediments are confined within and diverted ' through the casing into a tub on the deck of the barge which contains circulating water and any sediment transported with the circulating ' water. Nothing will be discharged to the water, and no drilling muds ' will be used in the drilling process. Soil samples will be collected 5 ' GULF OF MAINE RESEARCH CENTER INC. ' at approximately five-foot intervals with a split spoon sampler using standard penetration method test protocols. If field conditions ' warrant, more frequent sampling will be conducted. Samples collected during the geotechnical investigation will be taken ashore for ' evaluation. Soil samples will be placed in glass jars. The soil ' samples and rock cores will be sent to a geotechnical laboratory for testing. Any excess soil will be drummed on the barge and ' disposed of properly. At a later date, six sediment core samples will be obtained at ' three location (two samples per location) using a 8-foot gravity ' corer deployed from a boat. The samples will be contained in a liner placed inside of the gravity corer . When the gravity corer is ' returned to the boat deck, the liner will be removed, sealed and capped. The intact liner will be taken to an analytical laboratory ' for physical and chemical testing. The coring device will be decontaminated between locations with laboratory-grade, biodegradable tdetergent (e.g. Aloconox) , tap water, and seawater. As with the soil ' borings, the core samples will be collected along a 660-foot line trending northeast from the end of the existing outfall. ' The results of these investigations will be provided to the Salem Conservation Commission for their information. 1 1 1 6 1 GULF OF MAINE RESEARCH CENTER INC. ' 4.0 WETLAND RESOURCE AREA IDENTIFICATION ' The area to be investigated fulfills the Massachusetts Wetlands Protection Act definition of Land Under the Ocean. Because the water ' depth at the Site is thirty feet, the area is considered "Nearshore" ' Land Under the Ocean. No significant alterations to any Wetland Resource Areas are anticipated. 4.1 Definitions tThe following definitions are from the Massachusetts Wetlands Protection Act Regulations. 4. 1 . 1 Land Under the Ocean 310 CMR 25 ( 2)a ' "Land Under the Ocean" means land extending from the mean low water line, seaward to the boundary of the municipality' s ' jurisdiction and includes land under estuaries. 4. 1. 2 Nearshore Areas 310 CMR 25(b) ' "Nearshore Areas" of land under the ocean means that land ' extending from the mean low water line to the seaward limit of a municipality' s jurisdiction, but in no case beyond the point ' where the land is 80 feet below the level of ,the ocean at mean low water. 1 7 GULF OF MAINE RESEARCH CENTER INC. ' 5.0 WETLAND PROTECTION INTERESTS The Wetland interests at the Site subject to protection under the Massachusetts Wetlands Protection Act (MGL C. 131 5. 40) and its ' implementing Regulations ( 310 CMR 10 .00) are: ' - storm damage prevention ' - flood control - protection of fisheries ' - protection of shellfish Any activity proposed or undertaken within an area subject to ' protection under the Act which will remove, fill, dredge, or alter that area subject to protection under the Act requires the filing of ' a Notice of Intent ( 310 CMR 10. 02) . In addition, the State Regulations also indicate that no project shall have an adverse effect on rare vertebrate or invertebrate species that occur within ' resource areas. The Regulations ( 310 CMR 10 . 04, 10 . 59 ) define a rare species as any vertebrate or invertebrate officially listed as ' endangered, threatened or of Special Concern by the Massachusetts Division of Fisheries and Wildlife under 321 CMR 8 . 00. 8 ' GULF OF MAINE RESEARCH CENTER INC. ' Land Under the Ocean may be significant to storm damage ' prevention, flood control and protection of marine fisheries and shellfish. Authorities may issue an Order of Conditions for work in ' Land Under the Ocean provided that no alterations are made in the ' ability of the Resource Area to provide the following functions: reduce wave action; provide sediment for coastal beaches and dunes; ' maintain water quality; maintain the particle size distribution of sediments; and, maintain fish and shellfish habitat. Any activities ' which create high levels of turbidity, release pollutants, increase the temperature and reduce the dissolved oxygen content of the water will be carefully regulated. 6.0 IMPACTS ' The project has been designed to minimize the impacts to the protectable Wetland Resource Areas at the Site. All performance standards outlined in the Regulations will be adhered to, as detailed ' below. 310 CMR 10. 25( 5) - The collection of soil samples by boring and gravity corer will not significantly alter the bottom topography. The sampling program described herein will result ' in the collection of ten, three-inch diameter samples ( four borings and six sediment core samples) . 9 I' ' GULF OF MAINE RESEARCH CENTER INC. ' 310 CMR 10. 25 ( 6 ) - The collection of samples will also result in no, ' or minimal adverse effects on marine fisheries habitat or wildlife habitat. The sampling will not change water ' circulation patterns; nor will it affect the eelgrass or ' widgeon grasses as these are not present in the sampling area. Changes to water quality will be minimal, and restricted to ' localized turbidity effects. Turbidity resulting from boring and gravity coring operations will be comparable to those from ' dropping and raising a large anchor. The area around the ' existing outfall does have a dense population of polychaetes including Polydora spp. , Spiophanes bombyx, and Prionospio ' steenstrupt. Because the sampling will disturb only a small area of the sea bottom (ten, three-inch diameter sample locations) , these species will not be adversely affected. 310 CMR 10. 25(7) - According to the most recent edition of the "Atlas of Estimated Habitats of State-listed Rare Wetlands Wildlife ( 1992) , the Site does not provide rare and endangered species ' habitat recognized by the Massachusetts Division of Fisheries and Wildlife, Natural Heritage and Endangered Species Program. Therefore no measures are necessary to protect rare and ' endangered species at this Site. 7.0 SUMMARY According to State Regulations, the Site contains the protectable Wetland Resource Area, Land Under the Ocean. Appropriate 10 ' GULF OF MAINE RESEARCH CENTER INC. ' care will be provided for the proposed activities within the Land Under the Ocean. ' The project complies with all performance standards of the Massachusetts Wetlands Protection Act and its implementing ' Regulations; therefore, the interests of the Act will be protected. 1 1 I' 11 I� 1 fat ,y c 2N.WX 77 f � >7'PI / t ; i The Site � 6 hi mr 11�(asand r 3 a$IIGPn .�RP�p 23 ir -' RoEk y� y � iQnfo` .' .� �" DollibeP •B L J KARBOR / . i 'R«k vch o •-� 4 a y yDFt s "L C1 1po�. o ✓ OL / ..ern PU if +f /•gy{p _ b i � •1dnMr 1 li Figure 1 , (F1 ) Site Location ' Base Map: USGS Marblehead North , MA Quadrangle 1 1 GULF OF MAINE RESEARCH CENTER INC. 1 i ' ATTACHMENT 2 SITE PLAN ' IDENTIFYING NUMBER: P1 1 1 II 1 i , 1 9% 4 .C�l2{ ,/7r/•Irfrlr�.1` `\� "tt\ r/UI � 1 Ilrl1 .� �lLll f/a '�u,yrn'.n1nlullmltualol``' �•� O a O 1!9 o Vill . c ° IF ti.. � ' r• 10......] ' •� � �• D 22 1i 1< ...... .•16 23 /Iloci 26 p 26 29 7 2- - 8 Cn 10 7 16 28 R 24: I' I 32 .f0 t y.. _' • • ` ■ .

An abandoned underground petroleum storage facility was discovered as a result of a ' magnetometer survey conducted at the site. An NPDES Permit Exclusion was obtained to dewater the excavation as part of the removal of four 20,000 gallon tanks. Investigations included designing a soil boring program to characterize the vertical and lateral extent of soil contamination associated with the power plant operation. A monitoring well network was installed to determine the hydrogeologic parameters of ' the unconfined aquifer and the potential impact of the contaminants on the adjacent tidal river. Mr.Low has been responsible for managing numerous site assessments ' of commercial and industrial facilities including investigations to determine the presence or absence of oil and hazardous materials in accordance with MGL Chapter 21E and the implementing regulations ' contained in 310 CMR 40.00, the Massachusetts Contingency Plan (MCP). Waiver of Approvals were obtained for many of these sites to conduct comprehensive site investigations,investigate the potential i ' remedial options, and perform remedial activities including soil vapor extraction, soil removal, and groundwater pump and treat systems.
