Merrimack Engineering Services, Inc. 66 Park Street Andover, MA 01810 Re: Wastewater Treatment and Dispersal System Plan for 23 Forest Street Map 106A, Lot 69 Dear Mr. Nemohenck: The proposed wastewater system design plans for the above site dated December 2, 2006 and received on December 14, 2006 has been reviewed. Unfortunately, they cannot be approved until the following items are corrected. The specific section in Title 5: 310 CMR 15.000, or North Andover regulation that is not met by this design follows each item. 1. Please provide a description of the proper method of abandonment of the existing _4 wastewater system— 354 A2.] Please clarify whether you intend to specify an effluent filter or not. The plan details are unclear. If to be used, the plan must indicate that annual maintenance is required, and must indicate a brand and model which is approved for use in Massachusetts 3. Please indicate the distribution box is to have all outlets discharge at the same elevation— 232 4. Please indicate the requirement for an inspection ports) in the soil absorption system and provide appropriate detail specifications—240 5. Please clarify the specifications and labels for the gravel-less chambers indicated. The design appears to be based on the Infiltrator-brand Quick4-model chambers, while the details are labeled for the Infiltrator-brand Standard-model chambers. This should be clarified. 6. Please provide for a primary (septic)tank detail which depicts the tees located beneath the access openings - 227 7. There is only one test pit in the leach area,however, since the soils seem very consistent we do not see a problem with this. This would require an additional soil test or a Local Upgrade Approval for only having one test pit in the soil absorption system area 1600 Osgood Street 14 ALTH DEPARTMENT liege 1 of 1 Building 0,Suite 2-36 -Mail: lieaIthdept@townofnortliaridover.com North Andover,MA 01845 Phone:978.688.9540 Fax:978.688.8476 8.

This approval includes a Local Upgrade Approval for the request to have only one test pit within the area of the proposed system. This plan is valid for two years from the date of a septic system that did not meet the acceptable criteria in the state regulations. The design has been approved for use in the construction of an onsite septic system for a 4- bedroom house (maximum 9-room). 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 may reduce the time period for which this plan is valid. This approval is subject to the following conditions: 1. 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. 2. It is the responsibility of the applicant and/or the applicant's septic system designer, septic system 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 or imply compliance with any of the aforementioned requirement. 1000 Osgood Sbt eet, North Andover, l a ssachUsetts 01845 1"hone 078.088.0540 Fax 978,688,8476 Web www,tore offiortharrdover.coifl Your effort to provide a properly functioning septic system for your dwelling is greatly appreciated, The Health Department may be reached at 978-688-9540 with any questions you may have.

I don't like missing things either. The numbering of the plan in regards to the items missing was a great idea. I think sometimes we don't detail the item enough so that the engineer can know where we are coming from. Of course being too wordy can be a problem,but it will have to be so that we are on the same page. Some of the items you circled are basically 50% of what we need so I will try to be clearer. Our goal is to provide a plan that any installer can pick up and install,without any guessing on their part. This will mean fewer mistakes. You may feel that basically this is impossible, but we can only try. Though you may find some items nit picky, once some of them are changed on your CAD you will be set. I am returning your highlighted plan via mail so you can see what I am referring to. Also,please note we always need one original stamp and signature on a plan. 1. Please provide a description of the proper method of abandonment of the existing wastewater system- 354 correct - it is ff 12 on the plan 2. Please clarify whether you intend to specify an effluent filter or not. The plan details are unclear. If to be used,the plan must indicate that annual maintenance is required, and must indicate a brand and model which is approved for use in Massachusetts septic tank details say either a gcrs baffle or tee filter and the profile says what to do depending on which is chosen. We do not think it should be up to the installer to make this decision. I personally think the cnigineer would want what they prefer as it will definitely affect the systems function. There is no requirement to have a filter, so it is the engineers' ehoice. The clearer the better. 3. Please indicate the distribution box is to have all outlets discharge at the same elevation- 232 you highlighted the six inches for the outlet, but the elevations must be the same.

Please indicate the requirement for an inspection ports) in the soil absorption system and provide appropriate detail specifications- 240 The infiltrator end section is accurate, but an installer needs to know where in the field to place them. You asked what N. A. prefers. We have no rule; however, as an inspector I would encourage 1 port in cacti infiltrator row opposite;the d-box end. 5. Please clarify the specifications and labels for the gravel-less chambers indicated. The design appears to be based on the Infiltrator-brand Quick4-model chambers,while the details are labeled for the Infiltrator-brand Standard-model chambers. This should be clarified. OK 6. Please provide for a primary(septic)tank- detail which depicts the tees located beneath the access openings - 227 The narrative says" beneath covers" and yet your highlight of the detail shows deer not in the center. The drawing on the CAIN should be changed to look like what it says. 7. There is only one test pit in the leach area; however, since the soils seem very consistent we do not see a problem with this. This would require an additional soil test or a Local Upgrade Approval for only having one test pit in the soil absorption system area ok Sincerely,, f r S san Y.

Susan Sawyer, Public Health Director 1600 Osgood Street 'e Bldg. 20, Suite 2-36 North Andover, MA 01845 I€awl i RE: 23 Forest Street Dear Ms. Sawyer, I am in receipt of your letter dated February 28, 2007 regarding the above referenced site. I have revised the plan to specifically require an effluent tee filter. I have also added the elevation of the distribution outlets to the d. box detail as requested. Lastly, I have added the location of an inspection port to the plan view. With regard to the number of inspection ports, title S requires only one per s.a.s. and therefore only one is proposed. From a practical stand point the ports are provided to inspect the sand layer below the chambers, not the chambers themselves and providing one port for each row of chambers would not provide any added benefit. Why not require one port for each chamber? With regard to your comment regarding the d. box elevations all being the same, I fail to see how a contractor could not understand that the distribution outlets are to be constructed at the same elevation when the previous plan showed the outlet elevation in the profile,the d.box to be set level and all 5outlets at equal distances from the bottom of the box(6-in.). Do you have licensed installers who do not know that the distribution. outlets are at the same elevation? Isn't a test performed at final inspection to assure these elevations are the same?Flow equalizers were invented specifically for this reason. I think this point is very clear and known by any licensed installer even before looking at a plan. With regard to item#6 of your letter, it seems to me that you think the word beneath and center are synonymous. The location of the tees as shown on the CAD drawing is very deliberate. Covers are required to be 20 inches in diameter and the tees are required to be directly beneath the covers, any where beneath the 20 inch covers, not specifically in the center. This plan requires the tees to be beneath the outer edge of the covers. Covers are used for access to the tank for many reasons,not just to access the tees. The covers are used to pump and maintain the tanks,to visually inspect the interior of the tank,to access the tank with other equipment. Placement of the tees in the center of the covers impairs the ability to use the covers for all the intended purposes. This point has been argued to your department and to the reviewer in the past. I feel that this design meets the requirements of Title 5 and the N.A. BOH regulations and will provide any licensed installer all the necessary information to install the system properly. On behalf of our client, we respectfully request this design be approved as re-submitted. Yours truly, MERRIMACK ENGINEERING SERVICES, INC.
