There are a couple of things that need to be done prior to the final inspection. 1. The screw caps at the end of each line need a 1/4 " hole drilled in each so that when the pump is engaged the pressure can be verified. 2. There is no observation tube. 2 tubes are shown on the plan, someone will need to send me the ties from the house corners so I can add these to the plans. 3. The pea stone was not installed over the system stone. 4. The clean out at the house needs to be cut and capped. If you have any questions please let me know.

I have a question regarding the variance for not having a percolation test. The plan submitted has a variance request for section 15.245 which is the siting requirement for a percolation test within the soil absorption system area. I have looked through title 5 and other sections refer to how to perform a percolation test (section 15.104), but this section defines the fact that the system must be located where there is a percolation test and defines the rate. Although we indicate the variance on the plan item 3 states that we still need this variance. It would be helpful to me if you have a different opinion on what section needs to be referenced to let me know that. I don't want to keep submitting and getting the same comment in a letter 2 weeks later. I am going to re-word the variance request to the following. Allow the siting of a soil absorption system in an area without a percolation test meeting the requirements of Title 5 section 15.245. 1 plan to submit what is hopefully a final revised plan tomorrow and it would be helpful to have this resolved.

Polito OG� ,�, , Martin Suuberg Lieutenant Governor p Commissioner Standard Conditions for Secondary Treatment Units Approved for Remedial Use Last Revision Date: November 30, 2016 A Secondary Treatment Unit(STU)is an alternative technology that may be used as a component of an on-site sewage disposal system where soil or site conditions make conventional soil absorption systems more costly to construct or infeasible. A conventional system may be more costly to construct or infeasible where there is a shallow water table and/or limited area for the siting of a conventional system. As compared to a conventional system, in certain instances, an STU provides for higher loading rates(smaller leaching area) and may require less land area, potentially less fill, and less disturbance of the site. The System consists of an STU designed to reduce the organic material and solids in the wastewater which reduces the demand for treatment in the soil absorption system. A conventional septic tank precedes the STU unless exempt by the Special Conditions for a specific Technology. The use of an STU in accordance with this Approval for Remedial Use requires, among other things: • A Disclosure Notice in the Deed to the property(310 CMR 15.287(10)) (A Deed Notice template is available from the Department); • Certifications by the Designer and the Installer(310 CMR 15.021(3)); • A Massachusetts certified operator who has received training for the technology and is under contract for periodic inspection and maintenance (310 CMR 15.287(10)); • Periodic sampling,recordkeeping, and reporting, in accordance with this Approval; • Notification within 24 hours by the System Owner to the local approving authority of any System failure; • When pumping is required to discharge to the SAS, 24-hour emergency wastewater storage capacity above the elevation of the high level alarm; and • System Owner Acknowledgement of Responsibilities, in accordance with this Approval. This information is available in alternate format.Gall Michelle Waters-Ekanem,Diversity Director,at 617-292-5751.TTY#MassRelay Service 1-800-439-2370 MassDEP Website:www.mass.gov/dep Printed on Recycled Paper Standard Conditions for Secondary Treatment Units for Remedial Use Page 2 of 18 Revised November 30,2016 Definitions and References: The term"System"refers to the STU 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 these Standard Conditions applicable to all STU's with Remedial Use Approval,the Special Conditions contained in the Technology-specific Approval,the General Conditions of 310 CMR 15.287, and any other Attachments. The Conditions contained herein MUST be read in conjunction with any Special Conditions that are Technology-specific. I. Purpose 1. Approval for Remedial Use allows the use of the Alternative System only where the local Approving Authority finds that the Alternative System is for the upgrade or replacement of an existing failed, failing or nonconforming system with a design of flow of less than 10,000 gpd, where there is no increase in the actual or proposed design flow, and where a conventional system with a reserve area, designed in accordance with the standards of 310 CMR 15.100 through 15.255, cannot feasibly be built on-site. 2. The sale, design, installation, and use of the System shall be subject to these requirements for any system that submits a complete Disposal System Construction Permit (DSCP) application after the effective date of these Standard Conditions. Existing Systems and Systems for which a complete DSCP application was submitted prior to the effective date of these requirements shall not be subject to the design and installation requirements, however,the System Owner, the Service Contractor, and the Company shall be subject to all other requirements contained herein. 3. With the other applicable permits or approvals that may be required by 310 CMR 15.000, the Approval authorizes the installation and use of the Alternative System in Massachusetts. Except those provisions that specifically have been varied by this Approval, the provisions of 310 CMR 15.000, including the General Conditions of 310 CMR 15.287, apply to the sale, design, installation, and use of the System. 4. Unless stated otherwise in the Special Conditions that apply to a specific Technology, all the conditions contained in this document shall apply to secondary treatment units which have obtained Remedial Use Approval. (Special Conditions may be more or less stringent than the requirements of this document.) 5. Provided that the local Approving Authority approves the Alternative System in conformance with the Department's Technology Approval, Department review and approval of the site-specific System design and installation is not required unless the Department determines on a case-by-case basis, pursuant to its authority at 310 CMR 15.003(2)(e),that the proposed System requires Department review and approval. Standard Conditions for Secondary Treatment Units for Remedial Use Page 3 of 18 Revised November 30,2016 II. Design and Installation Requirements 1. Effluent BOD5, TSS and pH - The effluent discharge concentrations from the Secondary Treatment Unit to the SAS shall not exceed secondary treatment standards of 30 mg/L BOD5 and 30 mg/L TSS and the effluent pH range shall be 6.0 to 9.0. 2. The Designer shall be a Massachusetts Registered Professional Engineer or a Massachusetts Registered Sanitarian, including when designing systems for repair, provided that such Sanitarian shall not design a system with a discharge greater than 2,000 gallons per day. 3. Except where the Approval specifically states otherwise, the Alternative System shall be installed in a manner which does not intrude on, replace, or adversely affect the operation of any other component of the subsurface sewage disposal system designed and constructed in accordance with the standards of 310 CMR 15.200- 15.279. 4. Except where the Approval specifically states otherwise, the Alternative System shall include a properly sized and constructed septic tank, designed in accordance with 310 CMR 15.223 — 15.229, connected to the building sewer and followed in series by the Technology and the SAS; 5. 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 to allow for both the best feasible upgrade within the borders of the lot and the least 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 size of the SAS is necessary,the size of the SAS may be reduced up to 50 percent from the effective leaching area required when using the loading rates for gravity systems of 310 CMR 15.242(l)(a) for Systems sited in soils with a percolation rate of 60 minutes or less per inch, or for soils with a recorded percolation rate of between 60 and 90 minutes per inch,the loading rates of 310 CMR 15.245(4). (Alternatively, the effluent loading rates provided in 310 CMR 15.242(1)(b) for pressure distribution may be utilized, however, no reduction in the effective leaching area may be taken when using these loading rates, as stated in the regulation.); and/or b) If a reduction in the depth to 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; and/or c) If a reduction in the depth of the naturally occurring pervious material layer is necessary, a proposed reduction of up to 2 feet may be allowed in the four feet of naturally occurring pervious material layer required by 310 CMR 15.240(1)provided Standard Conditions for Secondary Treatment Units for Remedial Use Page 4 of 18 Revised November 30,2016 that it has been demonstrated that no greater depth in naturally occurring pervious material can be met anywhere on the site. 6. Any proposed reduction in the required depth to groundwater, specified in 310 CMR 15.212, may only be approved when: a) An approved Soil Evaluator who is a member or agent of the local Approving Authority determines the high groundwater elevation; b) No reduction is granted under LUA for setbacks from public or private wells, bordering vegetated wetlands, surface waters, salt marshes, coastal banks, certified vernal pools,water supply lines, surface water supplies or tributaries to surface water supplies,or drains which discharge to surface water supplies or their tributaries, is allowed; and c) 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). 7. The Alternative Design Standards for effective leaching area, depth to groundwater, and depth of naturally occurring pervious material contained in the Department's Standard Conditions for Secondary Treatment Unit Approved for Remedial Use shall not be made less stringent by the local Approving Authority under the LUA provisions of 310 CMR 15.405 or under the variance procedures of 310 CMR 15.411. 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. 8. Except those allowed under LUA and the Approval, any further deviation from the siting and design requirements of 310 CMR 15.000 for the remedial use of a Secondary Treatment Unit shall require the following: a) The applicant may propose the use of a Bottomless Sand Filter(BSF) as the means of on-site effluent disposal in conjunction with a Secondary Treatment Unit.

Systems designed for facilities in excess of 1,000 GPD typically require installation of a pretreatment or septic tank sized in accordance with the Company's requirements and constructed in accordance with 310 CMR 15.223 through 15.226. The Singulair Wastewater Treatment System,which includes both the Singulair 960 and Singulair TNT models with concrete tank and the Green models with plastic tank, is an extended aeration process providing flow equalization,pretreatment,aeration and clarification for treating sanitary wastewater. The Singulair treatment process takes place in a three-compartment precast concrete tank or similarly sized three-compartment plastic tank(Green models). The initial chamber removes gross solids, grease and oil from the wastewater by settling and flotation. The clarified liquid is aerated in the second chamber using a fractional horsepower, 1725 RPM aerator, operated with timer typically set at 30 min on and 30 min off,to mix and aerate the liquid and promote aerobic treatment. The TNT models are designed to be capable of also reducing total nitrogen in the wastewater with aeration timed to operate 60 min on and 60 min off. The third chamber contains the Bio-Kinetic unit, which provides additional filtration and settling using non-mechanical flow equalization. Sludge that settles in the third chamber is returned to the aeration chamber using a Bio-Static sludge return installed in an opening between the second and third compartments. The System includes a weather-tight enclosed control panel with aerator controls, manual reset circuit breaker, on-off automatic selector switch, adjustable timer mechanism and an audible/visual warning system to report malfunctions. The panel also contains the high water level override and high water alarm. The alarm and control circuits are each connected to an independent power source run from the main power source of the facility. The control panel is mounted in a location always accessible to the System operator. Conditions of Approval The term"System"refers to the STU 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 conditions applicable to all STU's with Remedial Use Approval, the General Conditions of 310 CMR 15.287, and any Attachments. For Secondary Treatment Units that have been issued Remedial Use Approval for the upgrade or replacement of an existing failed or nonconforming system, the Department authorizes reductions in the effective leaching area(310 CMR 15.242), the depth to groundwater(310 CMR 15.212), and/or the depth of naturally occurring pervious material (310 CMR 15.240(1)) subject to the conditions that apply to all Secondary Treatment Units Approved for Remedial Use and subject to the Special Conditions applicable to the Technology. singulair.doc NORWECO,Inc.—Singulair Bio-Kinetic Wastewater Treatment System Page 3 of 4 Renewal of Approval for Remedial Use Issued Date:November 07,2012 Special Conditions 1.

As requested by the Town of North Andover, we have completed our review of the design plan for the above property. The issues at the site are complex and the proposed design is as well. We will get a letter out with the details but the major issues which I wanted to frame in this email are as follows: • A number of a parameters of the DEP's policies for use of alternative treatment systems and alternative leaching systems are not complied with. I am attaching copies for your ease of reference. One of these parameters indicates that plastic chambers may only be used with percolation rates up to 90 mpi so the soil absorption system will need to either be re-designed or variance relief sought • The relief for no percolation test sought as a Local Upgrade Approval will need to be a variance to Title 5, not an LUA. Sieve analysis are only acceptable when high water precludes the possibility of performing such a test • The loading rate will need to be at least 0.15 or perhaps less, but not 0.20. This might impact the design of the soil absorption system or might necessitate additional variances if 0.20 is desired to be maintained as the loading rate • The use of both a Secondary Treatment Unit(STU)and a leaching chamber system cannot be done by right. This requires approval under the STU remedial use policy • The relief requested as an LUA to reduce water table offset by 2' is not authorized under the LUA standards, but is indicated in the STU remedial use policy • Compliance with the variance standards in Title 5 will need to be demonstrated in writing We will get a more formal letter out but the above is a series of major items to consider so I wanted to share them with you in this context rather than buried in a letter. Please let me know any questions you might have or if I can assist with anything.

I will drop off hard copies and the application fee before noon today. As I mentioned previously this property was difficult to perc and we aborted the perc test while performing the on site soil testing. While on site I took a soil sample and it has been sent to U-Mass for analysis. As soon as I have the results back I will send them along. For the purpose of design I have included a pre-treatment system and have asked for a local upgrade for the use of the sieve analysis in lieu of a percolation test and for a reduction in the offset to groundwater. The leach field size has been based upon the lowest loading rate for a pressure dosed system. Although this design may not fall totally within the guidelines for Title 5 (No percolation test), I think we all need to remember the fact that the home was built in 1963 and the system has been disposing of effluent into the ground for 56 years without a breakout. It is safe to say that the system has probably been at, or just above, the water table and the effluent has probably not received the level of treatment that it should, but the soil accommodated the flow. The new system will provide a level of treatment far greater than was ever provided at this location before, and it will be raised above the water table. Based upon the past performance of the soil and its proven ability to absorb the effluent directed to it, it is reasonable to conclude that the soil will continue to accept the effluent without endangering public health. I understand that this is a complicated design and it may be best if we can have a face to face meeting to discuss the design and permitting for the system. The owners would like to install the system this year as they are elderly and need to move to assisted care facilities, so I would like to avoid a protracted letter exchange to work out the issues. Please feel free to contact me so we can arrange a time to meet.
