A new permit must be obtained from this office for a well and/or on-site wastewater system NOT installed by the expiration date. If you have drilled the well, a well log must be sent to this office for documentation of the installation and to close the permit. If a licensed Professional Engineer has inspected the installation of the on-site wastewater system, the original as-built inspection report must be sent to this office for review, approval and documentation. Ail inspection reports must be submitted within 30 days of construction completion. When applying for a new permit, the fees are: $320.00 for an on-site wastewater permit; $120.00 for a well permit and $440.00 for a combined on-site wastewater and well permit.

Health & Human Services AUTHORIZATION TO DRILL Ins due on this con- al contract price. Date Addre~ Monday, October 26, 1998 Dear HHS staff, I witnessed the flow test on this well. It was done with a five-gallon bucket and was the most imprecise test imaginable. A heavy, drizzle-like mist was blowing up to 20 feet from the drilling orifice. This mist accounted for up to several gallons per minute not captured in the flow test. Several more gallons per minute were being ejected straight up before flowing down around the casing. This water was also not accounted for in the flow test. In summary, there was water running everywhere with perhaps half of it going in the bucket. I am not faulting the driller. He did a very good job drilling this well and I'm told that holding a five-gallon bucket under the drilling orifice is the normal method to test the production of domestic water wells in this area. However, as a professional scientist accustomed to carrying variance to the fourth decimal I find this method somewhat imprecise and hope that you don't place too much credence in flow-rate results generated by this methodology. If these reported flow rates are important to the consumer, I suggest you develop and require a standard method that is more precise.

( q ~ ~ ,~a, ~ o,., ~ ~ ~, ~, ~, ) Construction shall be in accordance with the approved site plan and design drawings, Municipal permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. The contractor shall be responsible for obtaining any necessary underground utility locates. Unless specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil settling. On all teachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. o Contractors installing wastewater disposal systems must be certified by the Municipal Health Department fbr system installations. Owners installing thek own systems must also receive prior approval from the Municipal Health Department. ~EPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. All standpipes on 'the septic tank shall extend a minimum of 12 inches above final grade. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page Two Lot 11, Block 3, Greatland Estaes Subdivision September 25, 1997 Septic tanks installed with less than 4 ft. of cover shall be insulated. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shall be to clean toward the leachfield. The second cleanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSORPTION TRENCH/DRAINFIELD INSTALLATION: Excavate the proposed trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level. If the sidewalls of the excavation become smeared, they must be raked or scratched (ruffed-up) before gravel (sewer rock) placement. Once the gravel is installed, the distribution pipe is to be installed level with the perforations faced downward. Gravel is then to be placed over the distribution pipe to provide a minimum of 2 inches of cover over the pipe. A silt barrier must be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing backfill. Monitor tubes shall be of four (4) inch diameter, installed approximately in the locations shown on the design, and extend a nfinimum of 12 inches above final grade. The portion of the monitoring tube extending through the gravel shall be perforated from the bottom of the trench to the invert of the distribution pipe. This is equivalent to the effective depth of the gravel as noted on the design. Bacld~l! over the final gravel layer must not be less than twenty-four (24) inches. Insulation must be installed when the back{ill depth is less than thirty-six (36) inches. The finish grade over the trench must be mounded to prevent the formation ora depression after settling. MINIMUM ._MATERIAL SPECIFICATIONS: 1. Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. Page Three Lot 11, Block 3, Greatland Estaes Subdivision September 25, 1997 The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Type of Pipe Perforated Solid o Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Femco, or equal). A permeable nontoxic silt barrier (Typar 3401, lV~rafi 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the ~f200 sieve. When sand is being used as a filter material, its gradation specifications must conform to current M.O.A. or D.E.C. requirements, which ever applies. INSPECTIONS: Typically there will be a minimum of three (3) inspections requked during the installation of the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfllled before this inspection. The second inspection must be conducted after the placement of the silt ban/er, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. 3. The final inspection is to occur upon final grading of the property. Page Four Lot 1 l, Block 3, Greatland Estaes Subdivision September 25, 1997 Often there will be more than these 3 inspections required. Especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer is to be contacted at lea3t 24 hours prior to the start of construction. If necessm'y, a pre- construction rn~ting will take place on-site. The h~specting en~neer will not coordinate, direct or contro! in any way the contractors a¢.ivities. The owner shall contract with the contractor to perfom~ the work outlined in these specifications and plans ~md in a~ordance with the attached M.O.A. permit. Them will be no contractu~ an'angement existing between the contractor and S & S Engineering. S & S Engh~ee~ug shall be the owner's representative and will inspect the work ~ stated above to document the contractors activities. Final acceptance of the contractors work rests with the owner and the M.O.A. S & S En[,fineefing shall ha~-e no liability 'to the oxvner or to others for acts or omissions of the contractor or any other p(~so~s performing work on this project or the failure of the contractor to ca..fy out the work in accordance with these consntmction docmments. S & S Engineedng's inspec~ng engineer will not be responsible for the construction metros, rnethods, teclmiques~ sequence, procedures or the saibty precautions inddent to this project.
