Design Criteria / Requirements: (1) System sized for repair of a one bedroom residence, as directed by Dave Ferris of DEP, (1) No garbage disposal shall be connected to the system. per a July 2,1999 phone call. (2) Septic tank/sewage basin shall be inspected and maintained according to 310 CMR (2) House is located on Baker's Island, 10 miles off the coast of Salem. There is no electric 15.300 and applicable local requirements. The tank shall be pumped entirely of its service on the island. There is no water supply, other than rainwater catchment and water contents at the end of every season. carried by hand from a community well. (3) Biodegradable soaps, detergents and non -chlorine bleach (such as hydrogen -peroxide) (3) Existing conditions, property boundaries and topographical survey taken from plans are recommended. entitled "Steve Willard Title V" dated December 1998 by SP Engineering and survey work W/N done by Lowell Robinson, Registered Professional Landscape Architect on June 8, 1999. V. Design Calculations: ll. Variances Requested: (1) Elevation of SAS SUSTAINABLE STRATEGIES The ESHWT elevation used to determine the SAS bottom elevation was found at deep hole (1) 15.211 (1) Minimum Setback Distances: The basement of the structure is a crawl space. #1 (top of hole between the 40.0' and 41.0' contour, ESHWT at 24" below grade). The This is treated as a Slab Foundation, according to a August 7, 1999 phone conversation with design ESHWT elevation shall be 38.0' (using the lowest elevation possible as the limiting Claire Golden, in the NE Regional DEP office. The variance requested is from the 10' setback elevation). Therefore, the bottom of the proposed leaching area shall be 41.0'. This required from the perimeter of the crawl space. The proposed septic tank/sewage basin is provides a 3' vertical separation between the ESHWT and the bottom of the SAS bed. located within the crawl space, under the house. There is a 5.62' vertical space under the house, which provides sufficient space for installation, access and maintenance. The septic (2) Design flow: tank is only partially buried, leaving 0.91' of the tank exposed above grade. This placement (per Title 5) of the septic tank is necessary due to the limitations of the site, especially the depth to ledge. 110 g/BR/d * 1 BR = 110 gpd* .60 = 66 gpd** Placing the tank under the house provides protection of the basin from environmental elements, **with composting toilet, a soil absorption system can be designed to accommodate 609/0 as well as protection from UV light. The tank shall be vented according to 248 CMR 2.16 Vents of daily design flow, resulting in a daily design flow of 66 gpd. and Venting, prevent sewage gases from entering the residence. Cbecked by (3) SAS area calculations (2) 15.212 Depth to Groundwater: The proposed system has a vertical separation of 3' from The most restrictive percolation rate found in the SAS area is 6.7 min./in. the bottom of the stone underlying the SAS to the ESHWT. This distance is sufficient in this The most restrictive soil type found in the SAS area is loam (soil class II). case due to the limitations of the site and the fact that we are treating graywater only, using Thus, according to 310 CMR 15.242, the design LTAR is 0.6 gal/sq.ft./day. a composting toilet to separate the blackwater. Therefore, the required SAS area is 110 sq.ft. (3) 15.223 Septic Tanks (1): The effective liquid capacity of the septic tank is 289.51 gallons. The SAS is configured in a 10' x 11' bed, with the bottom area utilized for calculating This is 439% of daily design flow of 66 gpd, well over the 200% requirement. The site has effective leaching area. serious physical limitations such as the lack of power service to the island, the need for the tank to be barged or floated to the site, then carried by hand over the island to the property, and The reserve area is exactly the same size (110 sq.ft) and configuration and is located on the the limiting factor of depth to ledge/bedrock. The suitable tank for this application is one sized west side of the house, over test pit #2 (with a perc rate of 5min/in, Class 'II Soils, with a for retention of 200% of daily design flow, without the restriction of the minimum of 1500 LTAR = 0.6 gal/sq.ft./day). gallons. We have provided over 400% times the daily design flow for further protection. (4) Septic tank and pump chamber buoyancy considerations (4) 15.223 Septic Tanks (4): A variance is requested from the five foot diameter requirement for The closest deep hole to the septic tank is #1, with an ESHWT of approximately 2' below a vertical cylindrical septic tank. The septic tank is a vertical cylindrical sewage basin, with a existing grade. The existing grade elevation in the area of the septic tank is 41.74', yielding diameter of four feet. The case for this smaller sized tank is made above in the variance request a ESHWT at 39.74'. The bottom of the proposed septic tank elevation is 39.91', thus from 15.223(1). no portion of the septic tank is in groundwater at any time during the season, and therefore buoyancy forces are not relevant to consider on the septic tank, the tank will not float. (5) 15.227 Placement and Construction of Tees (2): The separation of the inlet and outlet tees ' does not exceed the liquid depth of the septic tank. The liquid depth of this tank is 3.08' The tees VI. Design Specifications (in approximate wastewater flow order) have a horizontal separation of 2.33'. This is the largest separation available in this sized tank. Argument for reduction of required tank size is made in variance request # 3, from 15.223 (1).

This will protect the public health, safety, and the environment. A humus/composting toilet shall manage blackwater. This is a seasonal residence, with no pressurized water service. Rainwater catchment and hand carried water sources exist. METHOD: Route the total graywater flow from the residence into a septic tank/sewage basin. The clarified effluent from the septic tank/sewage basin then flows via gravity into a soil absorption bed where final disposal and treatment of graywater takes place. Removal of solids and scum from the septic tank shall be accomplished by regular seasonal pumping of the basin, performed by a licensed septage hauler.

The application includes two plan sheets prepared by Sustainable Strategies, titled "Septic System Plan, Willard 1 BR Residence, Lot 117/118, Baker's Island, Salem, MA"" dated and revised October 28, 1999. A copy of the approval issued by the Salem Board of Health was also included in the application. The facility to be served is an existing 1 bedroom residence. The proposed system is to replace a cesspool. An engineer for the Department has reviewed this application for approval under Title 5, 310 CMR 15.000. The Department has determined that the application cannot be approved as submitted. The following is a summary of the technical deficiencies that remain to be addressed: 1. Resource areas, in particular, coastal banks as defined in 310 CMR 10.00, must be delineated on the plan showing appropriate setbacks where required to the components of the system as required by 310 CMR 15.220(4)(1); 2. Velocity zones must be delineated on the plan pursuant to 310 CMR 15.220(4)(1); and. 3. The impervious barrier to be used to prevent breakout of leachate must also address the increase in slope from 3:1 to 2:1 pursuant to 310 CMR 15.255, as this system is considered a mounded system. A lined clay barrier or other suitable impervious barrier, acceptable to the Department, which will also address the structural requirements of the increase from the 3:1 slope to a 2:1 slope must be shown on the plan.

This is treated as a Slab Foundation, according to a August 7, 1999 phone conversation with Claire Golden, in the NE Regional DEP office. The variance requested is from the 10' setback required from the perimeter of the crawl space. The proposed septic tank/sewage basin is located within the crawl space, under the house. There is a 5.62' vertical space under the house, which provides sufficient space for installation, access and maintenance. The septic tank is only partially buried, leaving 0.91' of the tank exposed above grade. This placement of the septic tank is necessary due to the limitations of the site, especially the depth to ledge. Placing the tank under the house provides protection of the basin from environmental elements, as well as protection from UV light. The tank shall be vented according to 248 CMR 2.16 Vents and Venting, prevent sewage gases from entering the residence. (2) 15.212 Depth to Groundwater: The proposed system has a vertical separation of 3' from the bottom of the stone underlying the SAS to the ESHWT. This distance is sufficient in this case due to the limitations of the site and the fact that we are treating graywater only, using a composting toilet to separate the blackwater. ' 15.223 Septic Tanks (1): The effective liquid capacity of the septic tank is 289.51 gallons. This is 439% of daily design flow of 66 gpd, well over the 200% requirement. The site has serious physical -limitations such as the lack of power service to the island, the need for the tank to be -barged --or floated to the site, then carried by hand over'theisland to the property; and the limiting factor of depth to ledge/bedrock. The suitable tank for this application is one sized for retention of 200% of daily design flow, without the restriction of the minimum of 1500 gallons. We have provided over 400% times the daily design flow for further protection. (4) 15.223 Septic Tanks (4): A variance is requested from the five foot diameter requirement for a vertical cylindrical septic tank. The septic tank is a vertical cylindrical sewage basin, with a diameter of four feet. The case for this smaller sized tank is made above in the variance request from 15.223(1). (5) 15.227 Placement and Construction of Tees (2): The separation of the inlet and outlet tees does not exceed the liquid depth of the septic tank. The liquid depth of this tank is 3.08' The tees have a horizontal separation of 2.33'. This is the largest separation available in this sized tank. Argument for reduction of required tank size is made in variance request # 3, from 15.223 (1). (6) 15.228 Placement of Septic Tank (1): Stable, level 6" base of gravel will be compacted by hand, due to the limitations of the site, which makes mechanical compaction a hardship. The septic tank will be placed on this base, sited under the house (which is elevated on footings with 5.62' clearance to existing grade, providing ample space (3.45' above tank) for access for inspection and maintenance, as required by 310 CMR 15.228 (3)). Due to the physical limitations of the site, as explained above, the tank will be placed such that the lower 1.83' height i3 buried, and the upper 0.91' height is above grade. he tank is a vertical cylinder constructed out of fiberglass. This tank has been specified because it is designed to hold a full liquid load (of 376 gallons) without additional structural support, and it is lightweight and can be lifted and carried by hand to the site. The system is to be used from mid-April to mid-October. The tank will be pumped out at the end of each season by a licensed septic hauler to prevent freezing of the contents and structural damage associated with this freezing. (7) 15.228 Placement of Septic Tank (2): The septic tank/sewage basin is equipped with two 20" diameter manholes with removable impermeable covers of durable material. Three manholes (as code dictates) will not fit on this size septic tank/sewage basin. However, the two covers provide adequate access for inspection and maintenance of the inlet and outlet tees. (8) 15.240 Soil Absorption Systems (1): A variance is requested, according to 310 CMR 15.415(2), to allow the replacement of the existing failed septic system with an on-site system in two feet of naturally occurring pervious material. There is no alternative for siting a system in four feet of naturally occurring pervious material anywhere on the site (as evidenced by deep observation hole testing). Connection to sanitary system or shared system are also not feasible options on Baker's Island. (9) 15.240 Soil Absorption Systems (5): The soil absorption system has been designed to serve a one bedroom dwelling following directions, conveyed in a July 2,1999 phone call, from Dave Ferris of the DEP, NE Regional Office. The site is an existing one bedroom, and designing for 2 or 3 bedrooms would require the design to meet the new construction criteria. In order to repair the existing system, the design flow must be for effluent from the existing one bedroom dwelling.

As described in the letter of September 10, 1998, and November 24, 1998 we are requesting a variance to the regulation 310 CMR 15,240 (1) which requires a 4' separation to groundwater. Since the site has only 28" of soil on ledge and groundwater was found at 26-28" down it is not possible or economically feasible to achieve a four foot separation to groundwater. The septic system design includes an existing Biolet mulching toilet and grey water treatment. The design is non -conforming because of site conditions and a Variance is requested in accordance with 310 CMR 15.415 (2). In response to the issues raised, the blueprint had been changed since the initial submittal in response to Mr. Fair's previous comments of October 6, 1998 and subsequent discussion, so some of the items noted (1-14) have been changed already. Specifically, 1. The modified Plan has been stamped by our sanitary engineer David L. Bramley P.E. 928098. 2. The Plan does not show topography and the site has not been surveyed. The thick scrub -cat claw, viburnum and poison ivy would make surveying very difficult. The only cleared area is the 63'x50' area around the house which is relatively level where the proposed leachfield is located and has a moderate slope -toward the ocean on each side. 3. There is no benchmark on the Plan because no survey was conducted. A benchmark will be set for construction of the system. 4. The Plan view was drawn to relative scale for the Title V inspection report. The site was only visited once before the docks were removed for fall. The pertinent dimensions and distances are shown on the plan. Ms. Joanne Scott Page 2 January 8, 1999 5. The site property covers two contiguous lots #117 and #118 which are now shown on the Plan. The septic system is located on Lot #117 and is bordered by Lot #118. 6. Because of limited access the septic tank is specified to be prefabricated plastic with a sealed top and bottom draw -off. A certified soil evaluator did not visit the site, however soil samples were taken and analyzed for grain size to determine classification and derived LTAR (Long Term Application Rate). The percolation tests were also conducted to observe actual soil conditions. 8. The observed groundwater is shown in the soil logs at 26' down. 9. The soil logs are shown on the Plan. 10. The hydraulic profile is shown on the plan and relative distances and slopes shown. The inverts are not specified because it is not known how deep the septic tank will be placed since ledge is present. We could provide inverts but it will change in the field. 11. We will note the variances requested on the Plan. 12. The soil absorption system was designed as a leachfield (not trenchs) based upon contiguous Class II materials and PVC distribution lines bedded in stone. There is less than desirable cover over the leaching pipes, due to limiting soil cover on the site. The two inch layer of peastone was inadvertently not shown over the leachpipe stone. This will be added to the Plan. 13. The design flow calculations are based upon the minimum (330 gpd) which would be for a three bedroom dwelling. This seasonal residence has only one bedroom and no running water. All water is hand carried to the site (no road) so that actual water use is very limited and likely to be less than 50 gpd. If the design were based upon 110 gpd, the septic tank would have a four day retention time and the leach trench calculations you provided (276 sf @ 0.60 gpd/so would equal 165 gpd SAS loading or 50% extra capacity. 14. The request for a variance was made in writing on November 24, 1998, a copy of the letter is enclosed. Abutters have already been notified twice by certified mail. Ms. Joanne Scott Page 3 January 8, 1999 I hope these comments have answered your questions. Overall, I feel that the requests for details and strict Title V compliance are excessive this process considering the following; 1. Because of the mulching toilet this is grey water system not a full scale septic system. 2. The site conditions, (shallow soil over ledge), dense thicket vegetation, etc., cause the system to be non -conforming. 3. It is a seasonal residence on an island without electricity, road access or running water. Please call if you have any questions on this material. We still would like to present this information at the Board of Health meeting scheduled for Tuesday 1/12/99, and discuss the alternatives. Very truly yours, SP Engineering, Inc. P4.pc'_�G Bruce M.

The items listed are included on the revised 1/11/99 plan which is enclosed. If there are any additional concerns we have asked Mr. Fair or Ms. Scott to contact us for changes. In specific response to the letter of 1/7/99, regarding the application for a greywater Disposal System Construction Permit the following items are presented: 1. The original design and plan had been stamped by a Sanitary Engineer David Bramley and the revised plan is been reviewed now. 2. Relative elevations have been shown for the cleared area around the house. 3. The bench mark is indicated as the top of the existing dry cesspool and is approx. 25.0 NGVD. 4. The plan view had been reduced to accommodate more information on the original sheet, and therefore was out of scale, however, the original size, (V 20' Scale) as submitted in Nov 1998, has been replaced on the plan. 5. 'The property lines (Lots 9117 & 9118) and all abutters are shown as taken from the tax map. The Ocean Avenue that is shown between the lots does not exist. 6. The septic tank would be plastic or FRP, constructed per ASTM Std. C1227-93 or equivalent and a minimum of 320 gal capacity. Ms. Joanne Scott February 4, 1999 Page 2 A soil evaluator has not visited the site, however Chuck Johnson of David Clark Co., could visit the site in the Spring to confirm existing conditions. In this case, the site conditions are poor and a variance is requested for groundwater separation. 8. The observed groundwater elevation and ledge has been noted on the plan in the soil logs. 9. The test pits are only 28" deep and there is basically one soil horizon over ledge, Class II rated 0.30 gpd/sf. 10. Inverts of the system hydraulic profile have been indicated on the plan relative to the benchmark and building floor. 11. The request for variance to 15.240 (1) is shown on the plan. 12 & 13. The plan detail was expanded to show a leachfield as designed. Even though this is a greywater system, the SAS is designed to handle three bedrooms at 110 gpd or 330 gpd. The septic tank is designed for 60% capacity per 15.289 (3). 14. We had requested in September Board of Health approval for a remedial upgrade. Since then we have requested a variance to 15.240 (1) and have notified the abutters twice by certified mail. If you have any questions on this information please feel free to call. We have also completed the respective DEP applications BRP-WP59b for a Board of Health approved variance, and the DEP Board of Health application for Disposal System Construction Permit.

NOTIFICATION TO IMMEDIATE ABUTTERS Application has been made for the intent to repair a septic system on a parcel of land located on Baker's Island LOCATION: Lot 117 with ocean frontage on the west side of Baker's Island PLOT: Lot # 117 OWNER: Steve Willard 64 Ome Street Marblehead, MA 01945 TYPE OF DEVELOPMENT: - Repair of an existing septic system for a one bedroom residence r NUMBEK OF STRUCTURES) (,,Y, , ; : , One one bedroom house. NUMBER OF UNIT(S): One 17 LIST OF VARIANCES REQUESTED: (1) 15.211 (1) Minimum Setback Distances: The basement of the structure is a crawl space. This is treated as a Slab Foundation, according to a August 7, 1999 phone conversation with Claire Golden, in the NE Regional DEP office. The variance requested is from the 10' setback required from the perimeter of the crawl space. The proposed septic tank/sewage basin is located within the crawl space, under the house. There is a 5.62' vertical space under the house, which provides sufficient space for installation, access and maintenance. The septic tank is only partially busied, lezving 0.9l'of the tank exposed above grade. This placement of the septic tank is necessary due to the limitations of the site, especially the depth to ledge. Placing the tank under the house provides protection of the basin from environmental elements, as well as protection from UV light. The tank shall be vented according to 248 CMR 2.16 Vents and Venting, prevent sewage gases from entering the residence. (2) 15.212 Depth to Groundwater: The proposed system has a vertical separation of Y from the bottom of the stone underlying the SAS to the ESHWT. This distance is sufficient in this case due to the limitations of the site and the fact that we are treating graywater only, using a composting toilet to separate the blackwater. (3) 15.223 Septic Tanks (1): The effective liquid capacity of the septic tank is 289.51 gallons. This is 439% of -.daily design flow of 66 gpd, well over. the -200%0; requirement. The site has serious physical limitations such as the lack of power service to the island, the need for the tank to be barged or floated to the site, then carried by hand over the island to the property, and the limiting factor of depth to ledge/bedrock. The suitable tank for this application is one sized for retention of 200% of daily design flow, without the restriction of the minimum of 1500 gallons. We have provided over 400% times the daily design flow for further protection. iL r (4) 15.223 Septic Tanks (4): A variance is requested from the five foot diameter requirement for a vertical cylindrical septic tank. The septic tank is a vertical cylindrical sewage basin, with a diameter of four feet. The case for this smaller sized tank is made above in the variance request from 15.223(1). (5) 15.227 Placement and Construction of Tees (2): The separation of the inlet and outlet tees does not exceed the liquid depth of the septic tank. The liquid depth of this tank is 3.08' The tees have a horizontal separation of 2.33'. This is the largest separation available in this sized tank. Argument for reduction of required tank size is made in variance request # 3, from 15.223 (1). (6) 15.228 Placement of Septic Tank (1): Stable, level 6" base of gravel will be compacted by hand, due to the limitations of the site, which makes mechanical compaction a hardship. The septic tank will be placed on this base, sited under the house (which is elevated on footings with 5.62' clearance to existing grade, providing ample space (3.45 above tank) for access for inspection and maintenance, as required by 310 CMR 15.228 (3)). Due to the physical limitations of the site, as explained above, the tank will be placed such that the lower 1.83' height is buried, and the upper 0.91' height is above grade. The tank is a vertical cylinder constructed out of fiberglass. This tank has been specified because itis designed to hold a full liquid load (of 376 gallons) without additional structural support, and it is lightweight and can be lifted and carried by hand to the site. The system is to be used from mid-April to mid-October. The tank will be pumped out at the end of each season by a licensed septic hauler to prevent freezing of the contents and structural damage associated with this freezing. (7) 15.228 Placement of Septic Tank (2): The septic tank/ sewage basin is equipped with two 20" diameter manholes with removable impermeable covers of durable material. Three manholes (as code dictates) will not fit on this size septic tank/ sewage basin. However, the two covers provide adequate access for inspection and maintenance of the inlet and outlet tees. (8) 15.240 Soil Absorption Systems (1): A variance is requested, according to 310 CMR 15.415(2), to allow the replacement of the existing failed septic system with an on-site system in two feet of naturally occurring pervious material. There is no alternative for siting a system in four feet of naturally occurring pervious material anywhere on the site (as evidenced by deep observation hole testing). Connection to sanitary system or shared system are also not feasible options on Baker's Island. (9) 15.240 Soil Absorption Systems (5): The soil absorption system has been designed to serve a one bedroom dwelling following directions, conveyed in a July 2,1999 phone can, from Dave Ferris of the DEP, NE Regional Office. The site is an existing one bedroom, and designing for 2 or 3 bedrooms would require the design to meet the new construction criteria. In order to repair the existing system, the design flow must be for effluent from the existing one bedroom dwelling.

Box 1313 50 Beharrell Street Concord, Massachusetts 01742 USA Telephone: 978/369-9440 Tj / pa/ -M Addendum to Septic System Plan dated 9/1/99 Facsimile: 978/369-2484 E-mail: Sustainable@aics.net Web: http://www.ecological-engineering.com (1) In Section H of the Notes and Specifications, Variances Requested, #2, a vertical separation of 3' from ESHWT was requested. In actuality, we are asking for a variance to 2' from ESHWT, according to 310 CMR 15.212. Please note this change also in Section V, Design Calculations, #1, Elevation of SAS. This section should read: The ESHWT elevation used to determine the SAS bottom elevation was found at deep hole #1. The top of hole elevation is approximately 41.0'. ESHWT is 24" below grade, at approximately 39.0'. The bottom of the proposed SAS is at an elevation of 41.0'. This provides a 2' vertical separation between the ESHWT and the bottom of the SAS bed. (2) In Section VII of the Notes and Specifications, Installation and Construction Notes, add the following as (7): (7) For construction of SAS, all soil above elevation of 39.5' be removed in the area of the SAS, and a 5' area extending from all sides of SAS. This area is to be filled with material as outlined in 310 CMR 15.255 (3), to the elevation of the bottom of the system at 41.0'. Fill shall be comprised of clean granular sand, free from organic matter and deleterious substances. Mixtures and layers of different classes of soils shall not be used. The fill shall not contain any material larger than 2". A sieve analysis shall be performed on all materials according to 310 CMR 15.255 (3). (3) SAS Design and Area Determination: Baker's Island is an extremely restricted and unusual site. There is no pressurized water service, no electricity, and no ground transportation on the island. All water used on the site is hand carried from the community well, or collected rainwater. The residence is for seasonal use only. Initially the system was designed to accommodate a 3 bedroom home, with composting toilet. The engineer proceeded on that 3 bedroom design path, until a July 2, 1999 phone conversation with Dave Ferris, of the DEP. He redirected the design to serve a one bedroom house. He stated that we must design for a one bedroom, or else meet the code restrictions for new construction. The Willard's one bedroom house is equipped with a composting toilet. This eliminates the blackwater from the septic effluent. What remains to treated and dispose of is a small amount of graywater. The composting toilet, in accordance with 310 CMR 15.289 (3)(a), allows for a 40% reduction of the daily design flow to 66 gallons per bedroom per day.

Poole Sampled On: 7/09%98 Sample Recieved: 7/10/98 This information contained in this report is, to the best of my knowledge accurate and complete. Date: Laboratory Director: L BRAYLEY 1 I. General Notes: (1) System sized for repair of a one bedroom residence. (2) A copy of the Board of Health's and D.E.P.'s approval, including the restiction to serve a one bedroom residence, is recorded in the chain of title to the property served by the system. (3) House is located on (Baker's Island, 10 miles off the coast of Salem. There is no electric service on the island. There is no water supply, other than rainwater catchment and water carried by hand from a community well. (4) Existing conditions, property boundaries and topographical survey taken from plans entitled "Steve Willard Title V" dated December 1998 by SP Engineering and survey work done by Lowell Robinson, Registered Professional Landscape Architect on June 8, 1999, unless otherwise noted. II. Variances Requested: (1) 15.211 (1) Minimum Setback Distances: The basement of the structure is a crawl space. This is treated as a Slab Foundation, according to a August 7, 1999 phone conversation with Claire Golden, in the NE Regional DEP office. The variance requested is from the 10' setback required from the perimeter of the crawl space. The proposed septic tank/sewage basin is located within the crawl space, under the house. There is a 5,62' vertical space under the house, which provides sufficient space for installation, access and maintenance. The septic tank is only partially buried, leaving 0.91' of the tank exposed above grade. This placement of the septic tank is necessary due to the limitations of the site, especially the depth to ledge. Placing the tank under the house provides protection of the basin from environmental elements, as well as protection from UV light. The tank shall be vented according to 248 CMR 2.16 Vents and Venting, prevent sewage gases from entering the residence. (2) 15.212 Depth to Groundwater: The proposed system has a vertical separation of 3' from the bottom of the stone underlying the SAS to the ESHWT. This distance is sufficient in this case due to the limitations of the site and the fact that we are treating graywater only, using a composting toilet to separate the blackwater. (3) 15.223 Septic Tanks (1): The effective liquid capacity of the septic tank is 289.51 gallons. This is 439% of daily design flow of 66 gpd, well over the 200% (requirement. The site has serious physical limitations such as the lack of power service to the island, the need for the tank to be barged or floated to the site, then carries( by hand over the island to the property, and the limiting factor of depth to ledge/bedrock. The suitable tank for this application is one sized for retention of 200% of daily design flow, without the restriction of the minimum of 1500 gallons. We have provided over 400% times the daily design flow for further protection. (4) 15.223 Septic Tanks (4): A variance is requested from the five foot diameter requirement for a vertical cylindrical septic tank. The septic tank is a vertical cylindrical sewage basin, with a diameter of four feet. The case for this smaller sized tank is made above in the variance request from 15.223(1). (5) 15.227 Placement and Construction of Tees (2): The separation of the inlet and outlet tees does not exceed the liquid depth of the septic tank. The liquid depth of this tank is 3.08' The tees have a horizontal separation of 2.33'. This is the largest separation available in this sized tank. Argument forreduction of required tank size is made in variance request # 3, from 15.223 (1). (6) 15.228 Placement of. Septic Tank (1): Stable, level 6" base of gravel will be compacted by hand, due to the limitations of the site, which makes mechanical compaction a hardship. The septic tank will be placed on this base, sited under the house (which is elevated on footings with 5.62' clearance to existing grade, providing ample space (3.45' above tank) for access for inspection and maintenance, as required by 310 CMR 15.228 (3)). Due to the physical limitations of the site, as explained above, the tank Will be placed such that the lower 3.17' height is buried, and the upper 0.83' height is above grade. The tank is a vertical cylinder constructed out of fiberglass. This tank has been specified because it is designed to hold a full liquid load (of 376 gallons) without additional structural support, and it is lightweight and can be lifted and carried by hand to the site. The system is to be used from mid-April to mid-October. The tank will be pumped out at the end of each season by a licensed septic hauler to prevent freezing of the contents and structural damage associated with this freezing. (7) 15.228 Placement of Septic Tank (2): 'The septic tank/sewage basin is equipped with two 20" diameter manholes with removable impermeable covers of durable material Three manholes (as code dictates) will not fit on this size septic tank/sewage basin. However, the two covers provide adequate access for inspection and maintenamce of the inlet and outlet tees. (8) 15.240 Soil Absorption Systems (1): Avariance is requested, according to 310 CMR 15.41 S(2), to allow the replacement of the existing failed septic system with an on-site system in two feet of naturally occurring pervious material. There is no alternative for siting a system in four feet of naturally occurring pervious material anywhere on the site (as evidenced by deep observation hole testing), Connection to sanitary system or shared system are also not feasible options on Baker's Island. (9) 15.240 Soil Absorption Systems (5): The soil absorption system has been designed to serve:a one bedroom dwelling following directions, conveyed in a July 2, 1999 phone call, from Dave Ferris of the DEP, NE Regional Office. The site is an existing one bedroom, and designing for 2 or 3 bedrooms would require the design to meet the new construction criteria. In order to repair the existing system, the design flow must be for effluent from the existing one bedroom dwelling. )NOTES AND SPECIFICATIONS INCLUDES DESIGN CALCULATIONS AND CRITERIA ///House Footprint//X// Septic Tank/Sewage Basin: 3" vent stack Top of Tank ELEV = 44.33 Bottom of Tank 'ELEV = 40.33' Inlet INV ELEV = 43.58' 17 0.83' Existing Grade ESHWT 6" compacted gravel base III.

This will protect the public health, safety, and the environment. A humus/Icomposting toilet shall manage blackwater. This is a seasonal residence, with no pressurized water service. Rainwater catchment and hand carried water sources exist. METHOD: Route the total graywater flow from the residence into a septic tank/sewage basin. The clarified effluent from the septic tank/sewage basin then flows via gravity into a soil absorption bed where final disposal and treatment of graywater takes place.
