Mr. Strickland has agreed to modify his house plans and reduce the number of bedrooms in the residence to 3. Mr. Strickland has requested Thompson Environmental Consulting, Inc. (TEC) to revise the original on-site wastewater treatment and disposal system proposal to one for a 3-bedroom single family residence. Based upon previous soil investigations performed by TEC on the 1.113-acre lot, we have determined that a sufficient amount of"Provisionally Suitable" soil and Group 11 saprolite is available for the installation of a gravity flow Prefabricated Porous Block Panel System (PPBPS) for the initial system. Due to the site's proximity to Lake Norman, TEC is proposing that the repair system be a TS-11 Pre-Treated Accepted System to reduce the required horizontal setback to the lake from 50-feet to 35-feet. The drainfield product would be one with a state-approved 25% reduction in the required drainline length. Although this is a lot of record and is repair exempt, current policy requires that this system have a 100% repair area. Due to the request to reduce the horizontal setback to Lake Norman with the proposed repair area, TEC has performed a hydraulic assessment of the site in accordance with the "Recommended Guidance for In-situ Measurements of Saturated Hydraulic Conductivity by the Constant Head Well Permeameter Method and for Reporting Results, August 19, 2014" and the results listed in Table 1. Based upon this assessment, TEC feels that a site Long Term Acceptance Rate (LTAR) of 0.35 gal/ft2/day is well within the assimilative capacity of these soils. 1.„Test#,nfi;rli:' • iy'Depth ir” Measuith6al'li .1 j; '' 1 50 0.70 2 25 4.64 3 59 53.26 4 30 31.89 5 26 0.56 6 52 4.54 7 42 3.09 There is a private well on the site that will need to be properly abandoned by a licensed well contractor to meet required setbacks for this proposal. A new well will need to be drilled and must be kept a minimum of 100-feet away from any portion of the proposed septic system. Mr. Strickland would like to request that Catawba County Environmental Health (CCEI-1) consider issuing the appropriate permits for a subsurface wastewater treatment and disposal system based upon this revised proposal. 2 Location The subject property is located at 4869 Trestle Lane.

Primary Investigator's Credentials NC Registered Sanitarian No. 1208 NC Licensed Soil Scientist No. 1287 SC Certified Professional Soil Classifier No. I 1 1 NC Subsurface Septic System Operator No. 22199 NC Grade IV Wastewater System Installer No. 1762 NC Certified Wastewater System Inspector No. 17621 Professional Wetland Scientist No. 1346 Plans and Specifications A. Septic Tank 1. The septic tank shall be State approved (Section .1953 of 15A NCAC 18A), watertight, structurally sound, and a minimum size of 1000 gallons in capacity. 2. The septic tank shall be fitted with an approved effluent filter. 3. It is the responsibility of the septic contractor to thoroughly inspect the septic tank prior to accepting delivery to assure that the tank has had time to properly cure and is free of cracks or other structural deficiencies. B. Pipe, Fittings and Supply Line 1. All discharge piping, connectors and supply lines should be made of SCH 40 PVC. 2. All joints must be properly"welded" utilizing the appropriate PVC cement for each application. 3 C. Distribution Method 1. The system will be fed by a distribution box adjusted for equal distribution. D. Drainfield Installation 1. The proposed drainfield location has been marked on-site utilizing metal stemmed flags. Once this area has been approved by the county, the property owner/builder should mark this area and isolate it as much as possible from construction traffic. Prior to the system installation, the septic contractor shall contact the county for a preconstruction conference at which time the drainfield area will be re-verified. 2. Under no circumstances shall any construction take place within the drainfield area while the soil is in a wet condition. If the installer has doubts as to whether or not the drain field area is dry enough to begin construction, the environmental health specialist for this area should be contacted for permission to proceed with the installation. 3. The specified system is a Type II le pre-fabricated permeable block panel system— specifically the 16-inch high panel system manufactured by T&J Panel Wastewater Treatment System, Patent No. 4013559; telephone: I-800-222-2577. The installer must follow the manufacturer's guidelines for installing the T&J Panel System and should request an installation manual from the manufacturer prior to beginning construction. 4. The initial drain field consists of four (4) lateral trenches, each being 2-feet wide by 43.33-feet long. The fractional length line is to allow for the installation of ten (10) 46-inch long panels with 6 inches of space between panels. 5. It is essential that the lateral trenches be constructed on contour with the land, with each trench being excavated level from beginning to end. The use of a tripod mounted engineer's level is essential to assure that each trench is constructed as level as possible. !t is also imperative that the initial drainfield be kept outside of the 50 foot setback for the high water mark for Lake Norman. This area is currently surveyed in the field and may need to be re-staked prior to the system installation to assure that the contractor is outside of the 50-/bot setback. 6. The maximum trench depth for this system shall be 36-inches. Each trench shall be placed on a minimum of 8-foot on centers. 7. Once trenches are dug, the side walls shall be raked and a light dusting of lime applied. 8. Backfill the trench with 6 inches of sand and level to grade. Once leveled, place 1 x 4 or 6-inch boards on top of the sand the entire length of each trench. Once the grade boards have been set,the panels may be set into the trench. The panels should be placed 6-inches apart. 9. Once the panels have been set, line the top chamber of each panel with 10 — 12 pounds of clean particle sand (medium sand blasting sand). Coverage depth should be approximately 1 inch thick. Please note that this sand is not the same material specified for backfill. 10. Tar seal rope, or approved foam, should be placed in the "U" outs of each end of the panel to form seals. Once the tar rope is in place, the Schedule 40 PVC connectors can be added and the seal completed by the addition of more tar rope on 4 the top and sides of the pipe. Now that the connection and seals are complete, a block cap is placed on each end of the panel so that all openings are covered. II. Once the panels for each trench have been installed and the top of the panels closed, the trench is ready to be backfilled to the top with the sand used in the trench bottom. At this point, the trenches should be left open for the final inspection by the county environmental health specialist. E. Backfill 1. Backfill sand shall be clean, washed, medium sand that is naturally occurring and falls within the gradation of ASTM C-33 specification (used in the ready mix industry and is readily available). F. Final Landscaping 1. As previously stated, the final soil cover over the drainfield shall be a minimum of 6-inches deep. 2. The drainfield shall be shaped to shed rainwater and be free from low spots. 3. The drainfield area should be planted with grass as soon as possible to prevent erosion. The soil should be properly tilled, limed (if necessary) and fertilized prior to planting. After applying grass seed, the area should be heavily mulched with straw or other suitable material. G. Utility Conflicts 1. The builder and property owner must take special care in planning for water,power, gas, telephone and cable lines. These utilities shall be kept clear of all parts of the septic system and its proposed repair area. Improper planning for underground utilities can negatively impact the installation and, in some cases, cause irreparable damage and permit revocation. If there are any questions regarding preferred routes, contact CCEH as soon as possible. 2. Lawn irrigation should not be placed over the drain field area. Maintenance H. In General I. The homeowner must maintain the drainfield area through periodic mowing. The drainfield must not be allowed to become overgrown. 2. The septic tank should be pumped every 4 years or when the solids within the septic tank reach an elevation that is equivalent to 25 percent of the volume of the tank. In some situations, the tanks may need to be pumped more frequently. If using a garbage disposal, it is recommended that the homeowner has the septic and pump tanks cleaned out annually. 3. When it becomes necessary to clean the effluent filter, the filter should be removed and the accumulated debris washed back into the septic tank—not onto the lawn. 5 4. Any damp areas, leakages or malfunctions in the drainfield area should be addressed immediately. 5. Divert gutter downspouts and surface water runoff away from the septic and pump tanks.

Now with inclusion in the Sewage Regulations, the Panel System should be considered when a quality effluent may be needed, space is limited, usable soil is limited, or there are indications that at some future time space may be needed for other development. When there is a trend for added development such as additions to homes, pools, or other special landscaping development the T& J Panel System may prevent insufficient space later. As the environmental health specialist who is designing a system, and you can foresee such a trend of continued development, the Panel System may be an option the homeowner would like to utilize. As noted in the regulations a PPBPS is only permitted where soils are suitable,provision ability suitable, or reclassified provision ability suitable, however only one half of the area needed for a conventional system is required. This is one reason that the Panel System can help you use the best soils available on the lot. The system can be gravity fed, pumped to pressure manifold and gravity fed into the lines, or pumped to Low Pressure Panel lines. Most of the concepts for a Panel System layout are the same as for a conventional system. The biggest difference being the areal area needed and the quality of effluent being introduced into the ground. The T& J Panel system can be installed as either gravity, pump to gravity, pump to pressure manifold, or low-pressure pipe distribution system. When designing a pressure system the principles of low-pressure distribution are as described in the LPP manual. There is further discussion on pressure systems in the installer section of this manual. Conversion A three-bedroom house with a 0.4 gpd application rate (The first three steps are the same as for the conventional system). 1. 120 gallons per bedroom x 3 bedrooms = 360 gallons per day design flow rate. 2. 360 gallons flow rate/ 0.4 application rate = 900 sq. ft. of conventional trench bottom. 3. 900 sq. ft. / 3 ft. wide trench = 300 lineal feet of conventional system. This conventional layout requires 2700 sq. ft. of area on the lot with another equal area of repair space for a total of 5400 sq. ft. of suitable usable area. To calculate the size of the T & J Panel system , the above calculations must be made with an additional fourth step as described in (the T & J panel system). 4. 300 lineal feet of conventional system x 0.5 for a 16 inch high Pane System = 150 lineal feet of T&J Panel System. A Panel System requires only a 1200 sq. ft. area on the lot for the system with an equal area for repair,for a total of 2400 sq. ft. . With the panel system the installation and repair can go into the same area as the initial area required for a conventional gravel trench system. 15 Windows Effect To prevent hydraulic overload in the soil areal space should always be a consideration for any system, however, it is especially notable with the Panel System as with any system that reduces the size of the areal area drain field. The following is a simplistic example of this concept _ T ' CORRECT INCORRECT While both systems have the same lineal footage of trench the incorrect diagram is not a desirable design. The effluent must pass through the area A-A' which can cause a strain on that area and even a failure because of hydraulic overloading. Distribution Another extreme would be the use of a long single trench fed from only one end. In the first example, below the areal space is good and the chance of hydraulic over loading is greatly reduced. However, down line distribution in the panel line will not give optimum treatment. ■ 1111.1 roiroc-7. „ CORRECT INCORRECT In the lower example we see that the trench has been fed from multiple points. Because the Panel lines are put in as level as possible, never exceeding 1/4 inch of drain line fall in 10 feet of run,they feed both ways equally. T & J recommends that no gravity line exceed 50 feet, unless it is fed from multiple points. In both of these examples, we are specifying the Panel System, but the logic applies to the conventional system as well. 16 flow To Determine Number of Panels To calculate the number of 16 inch high panels needed for a 150 foot line, multiply 150' x 12" = 1800" then divide by 52" which is 46 inches for the panel and 6 inches for the space between the panels in the trench. 1800" /52" = 34.6 panels, so you would call for 34 panels. (A material order chart is included in the installer section of this manual.) If there is to be more than one trench, the sizing of the lines should be as equal as possible with as close to the same number of panels in each trench as is practical. Environmental Health Specialists should show the panel as small blocks on the line of the trench. Backfill Backfill sand shall be a clean, washed, medium sand that is naturally occurring and falls within the gradation of ASTM C-33 specification. This specification is one that is used in the ready mix industry and is readily available in all areas. The second type of sand that you will need is a clean particle sand to coat the bottom of each panel's top chamber with a bed of sand one inch thick. This sand is a medium grade of sand blasting sand. Each one hundred pound bag should cover eight panels. Backfill sand calculations should be taken from the material sheet. Tar Seals The two drawings below illustrate the inner and outer seal. Note that while the outer seal is a complete seal, the inner seal is only up to the top of the connecting pipe. This is to allow for over flow of the effluent at pea k useperiods into the lower air chambers. At this point the air chamber become additional storage chambers for the effluent.These seals can be inspected by lifting the caps at the ends of the panels while inspecting the system installation J t �l~ INNER and OUTER SEALS 17 Trench Preparation Trench grade should be established so that backfill cover will be four to six inches over the tops of the panels. (Note on several slopes system depth should be adjusted to protect against brakeout of effluent) In clay type soils the trench sidewalls should be raked to bring slicked over areas back as near to original structure as possible. A light dusting of lime on the sidewalls will help the system to continue the brake down of solids. Final Inspection The following lists of points are things that an inspector should look for when issuing a completion permit. I) Is depth of the panels within guidelines? 2) Are drain lines level or less than I/4-inch fall in ten feet? 3) Have seals been properly constructed? 4) Was the proper sand used in the trench backfill? 5) If in clay type soils were the sidewalls raked and limed? 18 Installer The Panel Block System Generally, on level open land, a Panel System can be installed in about the same time as a conventional system; however traditionally, Panel Systems have been installed where space and topography have restricted use of a conventional system. For this reason Panel System installations have required more time. Many installers enjoy the change of working with panels, not handling gravel, and the satisfaction of knowing a system being installed where previously a conventional system was not possible. Ordering Materials Enclosed on following two pages you will find an order sheet for the T & J Panel System and a materials chart for 16 inch high Panel System. The distributor in your area will lead you through these sheets when ordering or pricing the system. For information on the distributor located closest to you call 704-924-8600. After ordering, your panels will be shipped to the job site banded together on pallets. Installation Tips Installation for multiple line systems should begin in the most confiding area and be worked to the more open areas. �Ir�rs } tl -� 1 G frYcgt Q.f ( j � � t; t i ., LAKE Above is an example ofa multiple line installation. As you can see the installation should begin with the line marked 1 and proceed to 2, 3, then 4. This procedure will greatly ease material handling and backfilling. (Note sections of the drain lines should be left uncovered to allow for inspection of lines when area is confined and return access to lines is limited) On the following page are two examples of drain lines on sloping lots. The first drawing shows the drain line going through a slope making the center of the line deeper in the ground. This is not a desirable situation. The second drawing shows the drain line going around the slope keeping around the slope keeping the trench depth and cover uniform for the entire length o the line. On slopes, care should be given to avoid cutting away valuable top soil in an effort to make straight lines. The Panel line should be installed on grade with the contour of the natural slope. Panel lines can be curved to almost any degree. 19 I 91C ., M- td I iH = -=.. L_4 iso i—.. ^. lib CORRECT INCORRECT Diiujin,, The Trench Start by shooting the grade and marking the contour. Then for a I6-inch panel add 28 inches to the shallowest or lowest grade that the trench must cross to obtain the trench bottom grade. Now dig the trench at the elevation derived, checking the grade frequently. The trench should be a minimum of two feet wide. With the trench open all sidewalls shall be raked to bring smeared areas back to their original structure before a light dusting of lime is applied. Now place a 6-inch layer of backfill sand in the trench and level to grade, then place a 1 x 4 or 6 inch board flat on its side on top of the 6 inch layer of sand. Once more check the grade of the trench by shooting the top of the board. Once the grade boards have been set. the panels may be set into the ditch by hand or using the backhoe. Each panel weighs about 155 pounds and placement by hand goes quickly. The panels should be placed about 6 inches apart in the trench to obtain equal spacing. Now place 10 to 12 pounds of clean particle sand (medium sand blasting sand) in the top chamber of each panel to form a bed of sand about one inch thick. Tar seal rope should be placed in the U outs to form seals as shown in earlier drawings. Once the tar rope is in place, a 24-inch section of two inch PR160 pipe is cut to span from the upper middle top chamber of the first panel to the upper middle chamber of the next panel. The tar seal rope that is used should be of tar or butyl that is soft and pliable to obtain a watertight seal. Now that the connection and sealing is complete a block cap is placed on each end of the panel covering all openings. (These will be delivered with the panels.) The cap block may well serve as an inspection port at some future date. The trench is ready to be backfilled to the top so the panel with the same backfill sand used in the trench bottom. With the sand to the top of the panel, trenches should be left for the sanitarian to inspect. Soil cover should be added after the final inspection. Most Panel Systems are currently used due to space considerations and caution should be taken to preserve suitable soil structure and site conditions. 20 DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES S''°/_L DIVISION OF ENVIRONMENTAL HEALTH PROPERTY ID M: ONSITE WASTEWATER SECTION COUNTY: SOIL/STTE EVALUATION A, ,d_ for OlN SITE WASTEWATER SYSTEM J-�6_(6 (2,3„,(3,)OWNER :Gt'am J / rtc-V IAA, PLICATION DATE ADDRFCS- q sit( L n DATE EVALUATED: G-/?-q PROPOSED FACILITY: ' (- PROPOSED DESIGN FLOW(.1949): 3 6 0 PROPERTY SITE • LOCATION OF SIT PROPERTYPROPERTY RECORDED: WATER SUPPLY: U Private 0 Public @ WeII D Spring D Omer EVALUATION METHOD: 0 Auger Boring a Pit D Cut 'WEE OF WASTEWATER Sewage D Indus:nal Process D /vErd 4 .'_74- ".__ rc-cca ............._.__._.. ... ..___ _...._,:-..... _.__:.-......::.—........_._. _t-;..
