TTY#MassRelay Service 1-800-439-2370 MassDEP Website:www.mass.gov/dep Printed on Recycled Paper Modified Certification for Remedial Use October 30,2019 Page 2 of 4 Presby Enviro-Septic Wastewater Treatment System Issuance Date: Revised September 26,2014,Modified October 30,2019 X283267 Technology Description The System is an alternative subsurface Soil Absorption System(SAS)that replaces a conventional SAS designed in accordance with 310 CMR 15.000. The System consists of an 11 5/8-inch diameter corrugated,high-density plastic pipe with a 9.5-inch interior diameter and a standard length per unit of 10 feet.The pipe is perforated with eight holes equally distributed around its inner circumference at each corrugation. Each hole has a plastic skimmer extending inwards.The exterior of the pipe has ridges on the peak of each corrugation and is wrapped with two layers of fabric material.The inner layer is a thick layer of coarse,randomly oriented polypropylene fibers.The outer fabric layer is a non-woven geotextile polypropylene. The System includes required connectors designed to connect pipe units together. The System also includes sand surrounding the pipe units,specified as concrete sand meeting the ASTM C-33 specification,also called System Sand.The System Sand must be placed with a minimum of (6")six inches below,(3")three inches above and(6")six inches to the sides of the pipe units. Conditions of Approval The term"System"refers to the Alternative Soil Absorption System in combination with the other components of an on-site treatment and disposal system that may be required to serve a facility in accordance with 310 CMR 15.000. The term"Approval"refers to the technology-specific Special Conditions,the Standard Conditions for General and Remedial Use Approval of Alternative Soil Absorption Systems (the `Standard Conditions'),the General Conditions of 310 CMR 15.287, and any Attachments. For Alternative Soil Absorption Systems that have been issued Remedial Use Approval for the installation of Systems to serve facilities where the site meets the requirements for new construction,the Department authorizes reduction in the effective leaching area(310 CMR 15.242), subject to the applicable portions of the Standard Conditions, and subject to the below Special Conditions applicable to this Alternative Technology. Special Conditions 1. The System is an approved Patented Sand Filter System for use as an Alternative Soil Absorption System. In addition to the Special Conditions contained in this Approval,the System shall comply all Standard Conditions for Alternative Soil Absorption Systems found here: https://www.mass.gov/doc/standard-conditions-for- alternative-soil-absorption-systems-with-general-use-certification except where stated otherwise in these Special Conditions. 2. This Approval applies to the installation of a System for the upgrade or replacement of an existing failed or nonconforming system,provided that the facility meets the siting requirements for upgrades,as provided in I1(7)and 1I(9) of the Standard Modified Certification for Remedial Use October 30,2019 Page 3 of 4 Presby Enviro-Septic Wastewater Treatment System Issuance Date: Revised September 26,2014,Modified October 30,2019 X283267 Conditions. For the upgrade or replacement of an existing failed or nonconforming system,all installed Systems shall also comply with the Notice requirement of paragraph II(23)and the transferee notification requirements of paragraph IV(1)of the Standard Conditions. The proposed use of the System shall also comply with any other Standard Conditions which pertain wholly or in part to upgrades of existing systems. 3. Alternative Design Standards—Provided that the Designer demonstrates that the impact of the proposed Alternative System has been considered and the design requirements of 310 CMR 15.000 have been varied to the least degree necessary so as allow for both the best feasible upgrade within the borders of the lot and the least degree effect on public health, safety,welfare and the environment,the local approving authority may allow any combination of the following alternative design standards without the need for granting a variance under 310 CMR 15.400 or obtaining Department approval: a) If a reduction in the depth of groundwater required by 310 CMR 15.212 is necessary,the depth to groundwater may be reduced by up to 2 feet,resulting in a minimum separation distance of two feet in soils with a recorded percolation rate of more than two minutes per inch and three feet in soils with a recorded percolation rate of two minutes or less per inch,measured from the bottom of the soil absorption system to the high groundwater elevation, only if; i. An approved Soil Evaluator who is a member or agent of the local Approving Authority determines the high groundwater elevation; ii. No reduction is granted under LUA for setbacks from public or private wells, bordering vegetated wetlands, surface waters, salts marshes, coastal banks, certified vernal pools,water supply lines,surface waters supplies or tributaries to surface water supplies, or drains which discharge to surface water supplies or their tributaries,is allowed; and iii. In accordance with 310 CMR 15.212(2),for systems with a design flow of 2,000 gpd or greater,the separation to high groundwater as required by 310 CMR 15.212(1) shall be calculated after adding the effect of groundwater mounding to the high groundwater elevation as determined pursuant to 310 CMR 15.103(3). b) If a reduction in depth of naturally occurring pervious material layer is necessary, a proposed reduction of up to 2 feet may be allowed in the four feet of naturally pervious material layer required by 310 CMR 15.240(l)provided that it has been demonstrated that no greater depth in naturally occurring pervious material can be met anywhere on the site.

In no case, shall the reductions in the effective leaching area,depth to groundwater, and depth of naturally occurring pervious material allowed under this Approval be made less stringent.Any reductions in the effective leaching area,depth to groundwater, and depth of naturally occurring pervious material allowed under this Approval shall not be combined with any reduction that may be allowed the procedures of Local Upgrade Approval or the variance procedures of 310 CMR 15.401-413. The Local Approving Authority may vary other design requirements under the LUA provisions of 310 CMR 15.405 or under the variance procedures of 310 CMR 15.411. 5. The System shall only be installed in bed or field configuration,as described in 310 CMR 15.252. The System shall not be installed in trench configuration and no sidewall area shall be considered in the total effective leaching area provided. The effective leaching area shall be the bottom area only(length times width)of the sand bed. 6. Systems shall be installed with differential venting for aeration and inspection access at end of each run of pipe, section or serial bed and whenever the System is installed under impervious surfaces. 7. Serial distribution laterals shall be limited to no more than 500 gpd with each lateral a maximum of 100 feet, and must be laid level. Multi-level systems shall not be allowed. 8. The Enviro-Septic proprietary product(ES)will be sized at a minimum of seventy (70)linear feet per bedroom(lf/br)and will not exceed 100 feet in length. 9. System component material specifications for the pipe,plastic components, fabric and sand shall comply with the specifications identified in the initial Enviro-Septic I/A technology approval. 10. Prior approval from the Department for any change from these specifications shall be requested in writing. 11. Any changes to the approved plans must receive prior Local Approving Authority (LAA) approval. Before a Certificate of Compliance can be issued by the LAA the System Designer must include any changes to the approved plan into the as-built plans. 12. Design,installation and operation shall be in strict conformance with the Company's DEP approved plans and specifications of Enviro-Septic Wastewater Treatment System Massachusetts Design and Installation Mannual Copyright September 2019, Presby Environmental,Inc., 310 CMR 15.000 and this Approval.
