New England Engineering Services, Inc. 60 Beechwood Drive North Andover, MA 01845 RE: 100 Raleigh Tavern Lane,North Andover, MA Dear Mr. Osgood, The proposed septic system design plans for the above site dated September 8, 2004 and received on September 10, 2004 has been reviewed. Unfortunately, it cannot be approved until the following items are corrected. Each item is followed by the specific section in Title 5: 310 CMR 15.000, or North Andover regulation which is not met by this design. 1. Please show the offset of the system to surface water. (3 10 CMR 15.211). 2. The plan includes the use of a DEP-approved wastewater pretreatment unit and gravel- less chambers (Infiltrator brand). The Design Data shows the a reduction of leaching area is calculated for both features. This is a"double credit" and is not allowed under Title 5. Infiltrator Chambers may be used, but are not allowed to reduce leaching field size when using pre-treatment. 3. The LTAR as given in this plan is 0.20 when it should be 0.15. The "Bio-Microbics Remedial Use Approval MicroFAST"approval letter states in the Design Standards (section 11.4): The System may be used in soils with a percolation rate of up to 90 min./inch. For soils with a percolation rate of 60 to 90 min/inch, the effluent loading rate shall be 0.15 GPD1 sq.ft 4. The dose volume for the pump chamber does not meet the minimum dose volume required by the calculations provided (109 gal —vs- 157.7 gal) (310 CMR 15.254(c)(2)). 5. Pump chamber does not specify a maximum cover. (3 10 CMR 15.221(7)). 6. Treatment tank does not specify compact base and stone beneath tank. (3 10 CMR 15.221(2)) 7. Access manholes are not specified on treatment tank-. (3 10 CMR 15.228(2)) 8. Cover over treatment tank (max &min) is not specified (3 10 CMR 15.228(1) & 15.221(7)) 9. Location of blower unit and vent for the treatment device is not specified. 10. Tanl<_size indicated on design plan is not in accordance with Micro-Fast approval documents as issued by the Massachusetts Department of Environmental Protection. 11. Please clarify your intended treatment unit as both MicroFAST and Single Home FAST are indicated on the design plan. 12. The tank detail provided does not have the inlet tee to the sewptic tank designed in accordance with standards in Title 5 (3 10 CMR 15.227) 13. Please include a copy of the approval letter for use of the treatment unit with subsequent submissions. 14. Construction note 8 should be removed, as it references a Distribution Box, which is not present on this plan. 15. Please clarify the notation to the existing septic tank and whether it is to be removed or re-used. 16. Please specify the tank loading (3 10 CMR 15.227) 17. Please provide water department records or other documentation to confirm the existing water line route as depicted. 18. Please provide a draft operations and maintenance agreement for the treatment unit and pressure distribution system. 19. Please indicate the date of wetland delineation, name of delineator, and whether this has been accepted by the Conservation Commission. Although not a reason for disapproval,the following items might be considered to aid the contractor in construction of this system: 1. Please provide a detail of the rip rap slope at the low side of the SAS. 2. Please provide a design squirt height on the plans. 3. This design might consider available credits when using a treatment unit under the Remedial Use Approval such as reducing the size or ground water separation. If such a credit is being utilized, please indicate this on the design plan. Please feel free to contact the office with any questions you may have. We look forward to working with you to obtain a septic system which will be in compliance with all regulations and assure protection of public health and the environment of North Andover.

These plans have been revised to address the comments of your letter dated September 28, 2004 as follows. 1, The surface water is some distance away but the swamp between the surface water and the project is to thick to negotiate and take an accurate measurement. A leader showing a distance of 100' +to the surface water has been added. -2. The design notes have been revised to reflect the proper computations. The Fast System has been used to reduce the required field size by 50% and the infiltrator credit has been eliminated. 3. The long term acceptance rate has been changed to 0.15 gallons per day in the design calculations. Although the design calculations have changed the size of the system remains the same. -4. The dose volume has been revised to a minimum of 5 times the system volume. 5. The maximum and min cover over the pump chamber have been specified, 6. The stone is specified beneath the treatment tank. 7. The access manholes are specified on the treatment tank. 8. The maximum and minimum cover over the treatment tank have been specified. ,,,.~9. The location of the blower unit and vent have been shown, 10. The tank size for the Micro Fast has been changed. 11. The treatment system is a micro Fast and has been specified as such in both locations. 12. The inlet tee design has been revised to meet title 5. 13. The approval letter for the fast treatment system is enclosed. 14. Construction note# 9 has been removed. 60 BE CHWOOD DRIVE-NORTH ANDOVER, MA 01845-(97 3)686-1768-(888)359-7645..

The water line was marked in the field as shown, however the records do not provide the detail of its location. A note has been added that the location will have to be verified in the field by the contractor and relocated if required. 18. A copy of the draft operation and maintenance agreement is enclosed. 19. The wetland delineator has been identified. The line has been accepted by the commission. Several additional comments were noted in the letter. The design squirt height has been added to the plans. The calculations were revised to reflect an additional comment. Your quick review of these plans would be appreciated since the owner is anxious to commence construction.

October 5, 2004,received October 7, 2004). In addition, at a Board of Health meeting held on September 23, 2004, the BOH members voted to approve a local upgrade and a local variance as follows: 1) Local Upgrade Approval -A reduction in the offset distance between the leach bed and a wetland from 50 feet to 32 feet 2) A Local bylaw variance approval -A reduction to the offset between the leach bed and a wetland from 100 feet to 32 feet The 4-bedroom design has been approved for use in the construction of a replacement onsite septic system. This general approval is valid for three years from the date of this letter and during this time a licensed septic system installer must obtain a permit and complete this work, and a Certificate of Compliance must be endorsed by the installer, designer and the Town of North Andover.
