Years of research, development and extensive "on system" experience have led to the many exclusive features of the Environment One Grinder Pump which makes it superior for low pressure sewer systems and ideally suited for single application uses. In accordance with good practice, the Environment One Grinder Pump is powered by a high-torque low - speed motor. Therefore, it runs quieter, lasts longer and uses less electric energy than high speed units with more horsepower. Electric energy consumption of the Grinder Pump is typically less than 20 kWh per month. The unique one-piece core assembly incorporates all of the working and control elements of the Grinder Pump. The core is interchangeable throughout the entire model line, simplifying on-site service and reducing inventories. All Environment One Grinder Pumps are protected by a two year limited warranty covering parts and labor. MODEL GP -210 Designed for a broad variety of applications where flows range up to 500 gpd. Can pump domestic wastewater more than a mile through 11/4 inch PVC pressure pipe or provide lifts up to 92 feet. • PUMP - semi -positive displacement type; 13 gpm at 35 it TDH; • PIPING CONNECTION - inlet for 4 inch DW V pipe; discharge 11 gpm at 92 ft TDH; easily handles temporary loads 50% is 11/4 inch MPT. above the nominal design head. • CONTROLS - non -fouling static sensor and pressure switch • TANK - 60 gal; corrosion -resistant, heavy duty, fiberglass system has no moving parts in contact with sewage; complete - reinforced polyester (FRP), suitable for indoor or outdoor use. ly self-contained - no external panels needed. • GRINDER - two hardened stainless steel cutters rotating at • CHECK VALVES - one provided, integral on discharge pipe in - motor speed in precision relationship to hardened alloy shred- side tank.

Both applicants have applied for a Corps permit to place fill at the edge of Fire Lake to meet design setback requirements for on-site septic systems. On-site septic design and setback requirements are regulated under a section of the Anchorage Municipal Code which is not under my authority. I have taken this opportunity to forward your request to the On -Site Systems Section of the Department of Health and Human Services who oversees such activities. I have asked that that section respond directly to your office. I will, as necessary, continue to act as the Municipality's contact for additional questions on this or other wetlands issues. I hope I have addressed this concern to your satisfaction. Please contact my office, at 343-4309, should you need more information. Sinc e Michael.

No. AK911031-17A Your application for a water quality Certification of Reasonable Assurance has been reviewed and lacks the following information: 1. Have you asked the Municipality of Anchorage, Department of Health and Human Service, On -Lot Services Section for a lot line to sewage system and a primary to alternative system distance waiver? The granting of these waivers would be an alternative to fill placement as this would allow the alternate septic trench to be located between the primary system and the lot line. This office will not consider certifying your Corps permit unless said waivers have been denied. 2. Before this office can determine if on-site sewage alternatives exist or what type of sewage systems can be place on the lot, we need to know the type of soils at the proposed system location, and if a subsurface water table or bedrock exists within 6' of the proposed system trench bottom. Thus, please provide us with a soils test results that provide this information. This information is also required by the Municipality before they will grant an on-site approval, thus our request will not cause you to incur an added expense. Said information may show that you will have to put in a larger system than proposed, thus requiring more fill, or that a waiver maybe granted, thus saving you the expense of fill placement. Jim DeWinter -2- November 7, 1991 3. Is the edge of easement shown on sheet 3 of 3 equivalent to the lot line, or does the lot line go to edge of road? What is this easement for [road, utility]? 4. How many bedrooms will the proposed dwelling have? S. Sheet 1 or 3 shows a fill area at the lake shore on the lot adjacent to your south lot line. At the present time, permitting action on this fill has been suspended. Has fill been placed in that area? If a permit is not granted for said fill, your proposed alternate septic trench would still be within 1001 of the lake even if your permit was granted. How do you propose alleviate this problem. We cannot process this application without the above information. We will ask that Division of Coordination [DGC] coastal zone consistency determination comment period deadline be extended if we have not received the information within 10 days of receipt of this letter. Please send DGC, 3601 "C" Street, Suite 370, Anchorage, Alaska 99503, a copy of your response. Sincerely, Com.
