Unfortunately,the plan cannot be approved until the following items are corrected. The specific section in Title 5: 310 CMR 15.000,or North Andover(NA)regulation that has not met by this design follows each item for your convenience. 1. Please provide a benchmark within 50-75 feet of the system(220(4)(q)) 2. Please adjust the design to provide for the minimum slope required for the building sewer(222(6)) Please provide volume calculations which include the flow back volume for the pump chamber(231(2)) 4. Please provide a pump performance curve(220(4)(x)) 5. Please provide the correct number of deep observation holes in the disposal area or request a Local Upgrade Approval(102(2)) 6. Please use leach trenches or provide an explanation as to why trenches were not used(240(6)) 7. Please specify the final grade over the leach field to be a minimum of 0.02ft/ft(240(10)). Please feel free to contact the office with any questions you may have. We look forward to working with you to obtain a wastewater treatment and dispersal system which will be in compliance with all regulations and assure protection of public health and the environment of North Andover.

Item#1 refers to a benchmark which is clearly shown on the plan as the top of foundation and is within 50 -75 ft. of the system components. We are unclear as to the reviewers comment. Item#2 refers to the minimum slope of the building sewer which is shown on the plan and does meet the minimum requirement and we are again confused as to the reviewers comment. Item#3 has been addressed and added to the plan. Item#4 has been addressed. See copy of pump performance curve submitted herewith. Item# 5 refers to the number of deep holes. Site conditions were such that holes were dug where possible. The location of the existing leach field precluded us from digging 2 holes which fall within the proposed s.a.s. Both holes represent consistent soil conditions and water tables and it is reasonable to assume that conditions are consistent within the area of the proposed system. It is unfortunate to require a Local Upgrade for this site when all the design requirements are met. Issuance of the L.U.A. is solely for number of test holes which could ultimately restrict the firture use of the property however a completed L.U.A Application is submitted herewith. Perhaps a deep hole could be performed at time of excavation inspection so as to eliminate the need for a L.U.A. Item#6 refers to the use of trenches and as we have argued in the past, construction of trenches in this situation is less feasible as a field. Trenches would require a greater area and associated cost and would be constructed in fill and not function as the code intended. Lastly, item#7 refers to the final grade over the system. The typical end section specifies the grading requirements and the plan view shows the existing/proposed contours which also represent the grading requirements. Both comply with Title 5 and we are again confused as to the reviewers' comment. We have enclosed 3 copies of the revised plan and respectfully request that the design be approved as re-submitted. We appreciate your prompt attention to this matter. Very truly yours, MERRIMACK ENGINEERING SERVICES, INC. William Dufresne Project Manager MERRIMACK ENGINEERING SERVICES,INC. ^ 66 PARK STREET m ANDOVER,MASSACHUSETTS 01£110 tkoRTH 1G � SSIS HIG H.WKN PUBLIC HEALTH DEPARTMENT Community Development Division April 25, 2008 David Burt 259 Granville Lane North Andover, MA 01845 Re: 259 Granville Lane, map 106A Lot 152, North Andover, Subsurface Disposal System Installation Dear Homeowner, The North Andover Board of Health has completed review of the onsite wastewater treatment and dispersal system design plans for the above referenced property submitted on your behalf by Merrimack Engineering Services dated April 24, 2008 and received by this office on April 22, 2008. The design has been approved for use in the construction of a replacement onsite wastewater system for a 4-bedroom(maximum 9-room horse) This plan is valid for two years from the date of a septic system inspection that did not meet the acceptable criteria in the state regulations, January 9, 2008. During this time, a licensed septic system installer must obtain a permit and complete this work, and a Certificate of Compliance be endorsed by the installer, designer and the Town of North Andover. In the event an imminent health problem such as sewage backup into the dwelling is occurring, the North Andover Board of Health(BOH) may reduce the time period for which this plan is valid. This plan includes an approval of a local upgrade approval (LUA) for the variance to 310 CMR 15 102(2), requiring a minimum of two deep hole tests within the primary leaching area. With this LUA, the Health Department accepts that the soil characteristics are likely consistent within the system area even though it does not meet the minimum requirements set by Title V. No additional action is needed on this issue. Please also note upon second review that the initial reviewer was found mistaken on observations listed on the disapproval letter and noted as#1, #2 and#7. Please disregard these items. Item#6 was addressed in the response letter for reasons given, which if listed on the plan would not have been challenged. The document submitted for#4 will be attached to the plan to provide information to the installer. This approval is subject to the following conditions: 1. The building sewer invert shall be checked prior to construction and the engineer shall be consulted if any adjustments are needed to the placement of the tank elevations. 2. Keep the attached Form 9b for your records 1600 Osgood Street,North Andover,Massachusetts 01845 Phone 978.688.9540 Fax 978.688.8476 Web www.towoofnorthandover.com 3. If site conditions are found in the field to be different from those indicated on the design plan and/or soil evaluation, the originally issued Disposal System Construction Permit is void, installation shall stop, and the applicant shall reapply for a new Disposal Systems Construction Permit (3 10 CMR 15,020(l)), 4. It is the responsibility of the applicant and/or the applicant's designer, installer or other representative to ensure that all other state and municipal requirements are met. These may include review by the Conservation Commission, Zoning Board, Planning Board, Building Inspector,Plumbing Inspector and/or Electrical Inspector. The issuance of a Disposal System Construction Permit shall not construe and/or imply compliance with any of the aforementioned requirements. Your effort to provide a properly functioning onsite wastewater treatment and dispersal system for your property is greatly appreciated. The Health Department may be reached at 978-688- 9540 with any questions you might have.
