A 6.0 application rate is used for the organic topsoil layer, perc’d by GEG at TH#1 for the side wall of the sand. The effective absorption area is 2(55’+5’+55’+5’)*0.5’ – (6’+6’+5’)*0.5 = 114 sqft. This is the nominal effective minus the area discounted during construction. For a 4 bedroom home at an application rate of 6.0, the required absorption area would be 100 sqft. There is approximately 550 sqft of absorption area on the bottom of the trench which is not considered. The soil at the bottom of the sand layer has an application rate of 1.0 based on the perc rate of 69 mpi at C&M TH-1.

The excavation was not opened and closed in the same day. While this is not in violation of the permit requirements, we have re -iterated to the installer that the excavation needs to be opened and closed in the same day or covered and heated during freezing conditions after OCTOBER 151h Concerns were raised regarding the placement of filter sand per plan. The filter sand was installed in the upper trench as shown in the attached profile views. We also note that a function of the sand appears to have been to provide additional treatment for the originally designed CAT II treatment system to treat the effluent quality similar to a CAT III system. It was not our intent for the drain field design to be changed, however the CAT III system already produces higher quality effluent, so the additional filtration is not needed. During inspection, we verified the excavation depth was up to 4' at the deepest point and as shallow as 2.5'. The max excavation depth was supposed to be 3', but the placement of additional sand at the deep (over -excavated) end of the trench mitigates concerns with over -excavation. During inspection of the installed distribution pipe, we observed that the invert of the pipe to be as shown on the profile drawings. This results in approximately 6' of the length of trench on the East end being ineffective because it was installed too deep into the topsoil layer. We are proposing to discount that absorption area and the area on the east end wall of the trench: (2x6' x 1' + 5'X1' = 22 sqft) Subtracting 22 sqft from the apparent 220 sqft of trench as designed, leaves well above the 100 sqft required. Note that the entire upper trench could be discounted as the lower trench would have 110 sqft of absorption area, still meeting the minimum requirements for the system. We perc'd a ML layer at the upper trench to confirm permeability. The percolation rate was 69 minutes per inch. This area will effectively convey effluent horizontally and vertically; however that is not currently considered in the design. The application rate for these soils would be 1.0. By inspection, the upper trench (as constructed) effectively has more absorption area than accounted for in the design. The attached soils log shows the location of TH — CM, TH-CM2 and the perc pit. Soils were only logged at TH-CM. TH-CM2 and the perc pit revealed matching soil conditions. Groundwater was not encountered in any of the holes. The soils in the perc pit were very wet. A traditional pre-soak was not performed because the soils were effectively pre-soaked naturally. We note that the ML layer was gray and is visually similar to CL. Close observation revealed the presence of mostly fine silts and sands with some apparent clay particles. The excavation of TH-CM shows that the west end of the upper field is more than 3 -feet above any impermeable layer as required. Groundwater monitoring in GEG Th -1 and the dry hole at Th -CM and Th -CM2 confirm that the upper trench meets groundwater separation distance requirements. The GEG perc pit apparently had water and pea gravel in it. These conditions were not replicated at the two closer testholes we excavated. The department raised concern that the upper field may encroach on the groundwater table. The required separation distance is 2 -feet. Based on the 2' water depth in the GEG perc pit near the west end of the trench, there is 2 -feet separation between bottom of sewer rock and the highest observed groundwater table. Our inspection of bottom of trench on 10/12/22 revealed DRY soils consistent with the soil log for TH-1. The ML layer observed was visually better than expected and contained some coarse sand in addition to the silt/clay sized particles. Groundwater was at a depth of approximately 5.5 -feet. The groundwater tube was removed in accordance with code requirements. After discussions with the department, it was determined that the upper trench was required to have segment lengths of 20 -feet or less. The distribution pipe on the upper trench was redone per plan. Additional notes: • The side slopes are to be 3:1 max for both trenches. • The Contractor verified that they filled the existing trench with sand as required. • The calculations attached to the MOA approval documents for the tank configuration indicate a factor of safety of 2.2 against flotation on an empty tank with water at the ground surface without the addition of supplemental ballast. These tanks have flanges to help prevent flotation. We are requesting a change order for the upper trench as -installed. We are not requesting a change order for the lower trench at this time. Thank you for your time in reviewing this change order request. Please do not hesitate to contact me at 907-854-5558 or by email cgbalzarini(o-),gmail.com with any questions or concerns.

Name of Firm Phone Engineer’s Printed Name Date C&M ENGINEERING CHARLES BALZARINI, PE 3/10/24 T"itrate Advisory Certificate of On -Site Systems Approval # OSC231311 Subdivision: GRECIAN HILLS, Block: 2, Lot: 6 A water sample revealed a nitrate concentration of 5.41 milligrams per liter (mg/Q. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells. Since nitrates are known to slowly increase, we recommend you monitor the water quality. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On -Site Systems Approval. From Northern Testing Laboratories, Inc. Nitrate is a negatively charged compound of nitrogen and oxygen, which is very soluble in water. Nitrate is not readily filtered or otherwise removed in the soil and can pass rapidly into ground water wells. SOURCE: Nitrate is a major component of fertilizer and wastewater. Often the nitrate is in the form of ammonia or protein first, which through contact with oxygen and certain bacteria, converts to the oxidized form known as nitrate. Sources of nitrate from wastewater include urea, ammonia cleaners, food solids, and bacterial cells. It may also result from the breakdown of organic matter buried in the soil. TOXICITY: Nitrate is generally not toxic to adults or children over the age of two or three years, but is associated with a potentially fatal infant disease called methemoglobinemia. In the digestive system of young children, nitrate converts to nitrite, which can pass through the intestinal wall into the blood stream. There it combines with the hemoglobin and interferes with the ability of the blood to carry oxygen. For this reason, methemoglobinemia is referred to as "blue baby" disease. The EPA limits the concentration of nitrate in public drinking water supplies to 10 mg/L. The standard has been lowered from a previous level of 45 mg/L set by the US Public Health Service and the World Health Organization. TREATMENT: due to its solubility in water and negative ionic charge, filtration and other common home water treatment systems such as softening or iron filtration does not readily remove nitrate. The best method for limiting nitrate in well water is source control. This can include avoiding overdosing of fertilizer near the well and maintaining good separation distances between septic tank leach fields and the well. A special anion exchange filter that contains a media with a strong affinity for negatively charged ions in water, or by a reverse osmosis treatment system or distillation can remove nitrate. TESTING: Nitrate analysis is usually done by one of the several "wet chemical" methods using a spectrophotometer to read the final color endpoint. Specific ion electrodes also can be used to detect the activity of nitrate in water. This laboratory uses several different wet chemical methods approved under the public water supply laboratory certification program. They also have test kits available, which the laboratory uses to perform an inexpensive "screening test", and with which the homeowner can monitor the change in nitrate levels from their well. They recommend comparing the test kit results against a certified analysis from the lab occasionally to verify the accuracy of the kit. We recommend using a specially prepared bottle that has been rinsed in hydrochloric acid for collecting samples.
