Allow the reduction in the offset distance between the bottom of the leach bed and the water table from the 5 feet required by the Title 5 section 15.212 to 4 feet. Local Variances: 1. Reduction in the offset distance between the edge of the leach field and the wetlands from 100 feet required to 70 feet. 2. Reduction in the leach field size,from the minimum 900 square feet required to 600 square feet. 3. Allow the use of a poly barrier in lieu of a buried concrete wall for slope reduction.

These plans are being submitted to address the two comments in your letter dated August 11, 1999. Each of the comments has been addressed as follows. 1. A detail of how the poly barrier will be connected to the retaining wall has been added to the plans. The detail specifies that the poly barrier shall be applied to the fresh bituminous waterproofing with a 24" overlap. 2. The system is the same distance from the property line as the previous plan. A hearing was held for this variance at a previous meeting. If you have any questions or need additional information please do not hesitate to contact this office. Sincerely, Benjamin C.

The following is a list of all the`Problem' areas and deficiencies Port Engineering has found. (Note that this design plan with revision date of 8/6/99 is different than the design plan with revision date of 5/20/99. The fast system and pressure distribution system has been eliminated. The new design is for a conventional leaching trench system with conventional septic tank, pump chamber system and dbox.) u The leaching bed will be closer to the property line than the setback requirement allows_ Thus the abutter must be notified by certified letter as per 310 CMR 15.405(2). (I missed this the first time.) L) Note 14 on sheet one states that a Professional Land Surveyor shall stake the southern lot line. This should be made a condition of approval. u There will be an impervious barrier completely encircling the leaching bed. The southern part will be a concrete retaining wall. The rest will be a poly barrier. There should be a detail showing how the poly barrier will be tied into the concrete retaining wall to make sure it is a waterproof seat.

The following is a list of all the `Problem' areas and deficiencies Port Engineering has found. • A 6-inch stone base must be under the FAST Septic tank. 310 CMR 15.221(2). • The Plan and Section A-A on Sheet I show the two laterals for the leaching field. By scaling off the plan and section, it appears that the intent is to have 5 feet between laterals, with 2.5 feet between the laterals and the edge of the leaching field. If this is true, then the"Leach Pipe Layout Plan View" on Sheet 2 is incorrect in showing the laterals as being 8 feet apart and only one foot from the edge of the field. • The pump chamber buoyancy calculations show only a 300-pound difference between the buoyancy force and the weight of the chamber and overburden. However the calculations are for only one foot of soil over the tank where the grading shown on the plan would place about three feet of soil over the tank. Therefore, if the grading and pump chamber are placed according to plan, there should be an adequate factor of safety in the buoyancy calculations. • The"System Profile" has a drafting error for bottom of bed elevation of 99.28'. All the other bottom of bed elevations have the correct elevation of 99.5'. o If the well is in fact only for irrigation, then only a waiver from the North Andover regulation is required (as outlined in the"Local Variances Required" note on Sheet 1). • One of the impervious barriers is proposed to be a 20-mil poly barrier. Written policy of the DEP entitled "Guidance on Maximum Feasible Compliance" addresses this issue: "Appropriate synthetic materials may be allowed, provided that the applicant demonstrates to the local approving authority that the material is 0 R T impervious, is designed to be buried without the integrity of the material being affected, adequate provisions have been made to ensure its support and to prevent ENG�NEEGING puncture during installation". If these provisions are met,then the impervious barrier should be adequate. ® Other local upgrade approvals and local variance requests are also noted. In my Civil Engineers& professional opinion the requests seem reasonable for the conditions of the lot.

Suite 22 North Andover, MA 01845 RE: 15 Forest Street North Andover, MA Dear Ben, Attached are my recommendations for the pressure distribution system for the Forest Street project. I have developed a lateral layout and orifice spacing for the bed size you have indicated on the plans (sheet 1 of 2, file 4264). The manifold and force main diameters are 2" and should drain back to the pump chamber and the laterals should be level. A single 0.25"orifice should be placed in the manifold. Note the orifice indicated in the end caps at the end of each lateral. These could be replaced with an elbow and a capped riser for flushing out the laterals. If you consider them necessary, place an orifice somewhere in the lower portion of the elbow. Also note orifice along the laterals are placed slightly offset from vertical. While I do not consider this design practice essential it seems to be a suitable method for eliminating orifice blockage. The pump size is indicated, and should meet the minimum discharge of 46.5 GPM against 11.3 feet of head. If you find a pump that is significantly different, please provide me with the specifications and I can rerun the friction losses. An oversized pump will produce more pressure head at the distal end. An undersized pump is not desirable. A small throttle valve can resolve any issues about an oversized pump. Calculations based on your system criteria indicate less than 5% difference in orifice discharge over the entire system. I have reviewed the bed layout shown in sheet 1. I think that a reduction in the bed area to 6' by 60' will get you to the same treatment results, provided the basal loading area remains the same. The benefit of this change is a reduction in the height of the retaining wall and associated costs for materials. The pressure distribution design would not change significantly by reducing the lateral spacing to 4 feet on center,(ie. use a 4 foot manifold versus an 8 foot manifold). I can make any modification to the lateral layout enclosed if you want me to. If you have any questions or would like digital copy of the lateral layout(in Autocad 14) give me a call.

Please use this form in all future applications for soil testing. Note that before any scheduling is done for the actual testing, there must be a signed approval on the form from the Conservation Conum*ssion. Once this has been received, a date for soil tests will be scheduled with the Health Department. In addition, the plan you submitted to the Health Department shows a proposed addition to the existing dwelling. Is this being proposed now? If the soil tests are for the purpose of adding an addition,it is considered new construction and conditions are altered. Please contact me for a discussion about this issue.

Additional documentation enclosed includes a copy of the plot plan with proposed test pit locations, a copy of the contract for design as proof that the owner has given permission to have testing done, and a check to cover the fee. I understand that soil testing season does not open until March 1,however I would appreciate you having the schedule process started so testing could be done as soon after March 1 as weather permits. The owner is having problems with the system and is going to have a backup if something is not done soon, Thank you for your anticipated cooperation in this matter. If you have any questions,please do not hesitate to contact this office. Sincerely, Benjamin C.
