Stevens NORTH CAROLINA ENVIRONMENTAL MANAGEMENT COMMISSION DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES RALEIGH RESIDUALS LAND APPLICATION PERMIT In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended, and other applicable Laws, Rules, and Regulations PERMISSION IS HEREBY GRANTED TO Town of Hillsborough Orange County FOR THE continued operation of a wastewater residuals land application program consisting of the application of up to 500 dry tons per year of final residual product, consisting of one part by weight of aerobically digested residuals and two parts by weight lime, from source listed in Condition 11.5; to approximately 817.28 acres of land in Orange County with no discharge of wastes to the surface waters, pursuant to the renewal application received on March 6, 2000 and a subsequent modification received on August 22, 2000 as well as the additional information received on October 30, 2000; November 2, 2000; February 1, 2001; and March 8, 2001; and in conformity with the project plan, specifications, and other supporting data subsequently filed and approved by the Department of Environment and Natural Resources and considered a part of this permit. This permit shall be effective from the date of issuance until February 28, 2006; shall void Permit No, WQ000001 I issued January 31, 1996; and shall be subject to the following specified conditions and limitations: I. PERFORMANCE STANDARDS The Raleigh Regional Office, telephone number (919) 571-4700, and the appropriate local governmental official (i.e., county manager/city manager) shall be notified at least 24 hours prior to the initial application of the residuals to a site so that an inspection can be made of the application site and application method. Such notification to the regional supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays. In addition, the Orange County Manager's office must be notified prior to the initial application so that they will be aware that the operation has commenced. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the sites are maintained and operated in a manner which will protect the assigned water quality standards of the surface waters and ground waters. The land application program shall be effectively maintained and operated as a non -discharge system to prevent the discharge of any wastes resulting from the operation of this program. 4. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or groundwaters resulting from the operation of this program. 5. In the event that the land application program is not operated satisfactorily, including the creation of nuisance conditions, the Permittee shall cease applying residuals to the sites and take any immediate corrective actions as may be required by the Division of Water Quality (Division). 1. 6. Some of the buffers specified below may not have been included in previous permits for this land application operation.. However, any sites or fields that are included in this permit, but were approved with different applicable buffers shall be reflagged to comply with the below buffers. The following buffer zones shall be maintained: a. 400 feet from residences or places of public assembly under separate ownership for surface application method; however, the buffer zone requirement may be reduced to a minimum of 100 feet upon written consent of the owner and approval from the appropriate regional office, b. 200 feet from residences or places of public assembly under separate ownership for subsurface residual injection method; however, the buffer zone requirement may be reduced to a minimum of 100 feet upon written consent of the owner and the appropriate regional office, c. 100 feet from any public or private water supply source, waters classified as SA or SB, and any Class I or Class lI impounded reservoir used as a source of drinking water for both methods, d. 100 feet from any streams classified as WS or B, any other stream, canal, marsh or coastal waters and any other lake or impoundment for surface application, e. 50 feet from any streams classified as WS or B, any other stream, canal, marsh or coastal waters and any other lake or impoundment for subsurface application, f. 50 feet from property lines for both surface and subsurface application methods; g. 50 feet from public right of ways for both application methods, h. 10 feet from upslope interceptor drains and surface water diversions for both application methods, i. 25 feet from downslope interceptor drains, surface water diversions, groundwater drainage systems and surface drainage ditches for both application methods. 7. A copy of this permit shall be maintained at the land application site when residuals are being applies during the life of this permit. A spill prevention and control plan shall be maintained in all residuals transport and application vehicles. Specific residual application area boundaries shall be clearly marked on each site prior to and during application. 9. No residuals at any time shall be stored at any application site, unless approval has been requested and obtained from the Division. 10. Maximum slope for residual application shall be 10% for surface application and 18% for subsurface applications. 11. When wastewater residuals are applied, the Class A pathogen requirements and site restrictions in 40 CFR Part 503.32(a) or the Class B pathogen requirements and site restrictions in 40 CFR Part 503.32(b), and one of vector attraction reduction requirements in 40 CFR Part 503.33 shall be met. Additionally, an evaluation must be performed which demonstrates the residuals ability to comply with this requirement. Upon request, a copy of this evaluation must be submitted including all test results and calculations. II. OPERATION AND MAINTENANCE REQUIREMENTS I . The facilities and application sites shall be properly maintained and operated at all times. 2. A suitable vegetative cover, as listed in Condition 11.4; shall be maintained in accordance with the crop management plan outlined by the local Extension Office, the Department of Agriculture, the Natural Resource Conservation Service, or other agronomist, and approved by this Division. 4. 0 7. An acceptable pH must be maintained in the soil, residual and lime mixture, greater than 6.0, on all land application sites to insure optimum yield for the crop(s) specified below. Most sites in this permit have been identified in the soil scientist's report as having high levels of copper and zinc. These metals pose a risk of leaching and/or toxicity to the plants at soil pH values lower than 6.0. The application rates of residuals be such that the following plant available nitrogen (PAN) rates for the specified crops shall not be exceeded: Crop PAN (lb./acre/yr.) Crop PAN (]b./acre/yr.) Alfalfa 200 Forest (Hardwood & Softwood) 75 Bermuda Grass (Hay, Pasture) 220 Milo 100 Blue Grass 120 Small Grain (Wheat, barley, oats) 100 Corn (Grain) 160 Sorghum, Sudex (Pasture) 180 Corn (Silage) 200 Sorghum, Sudex (Silage) 220 Cotton 70 Soybeans 200 Fescue 250 Timothy, Orchard, & Rye Grass 200 If the approved land application sites are to be double cropped (i.e., a crop in the spring and a second crop in the fall, with BOTH crops to receive wastewater residuals), then the second crop shall receive an application of nutrients at a rate of no greater than 50 lbs/acre/yr. This practice will be allowed as long as the second crop is to be harvested. if the second crop is to be planted for erosion control only, and is to be tilled into the soil, then no wastewater residuals shall be applied to these fields because the nitrogen will essentially be returned to the soil. No residuals other than the following are hereby approved for land application in accordance with this permit: Permit Volume Source County Number & tons/year) Town of Hillsborough WWTP Orange WQ0000011 500 The metal loading rates shall not exceed the following Cumulative Pollutant loading rates: The pollutant concentrations in the residuals which will be applied to the land shall not exceed the following Ceiling Concentrations (Dry Weight Basis): Parameters Kilograms Pounds Parameters per Hectare per Acre Arsenic 41 36 Cadmium 39 34 Copper 1,500 1,338 Lead 300 267 Mercury 17 15 Nickel 420 374 Selenium 100 89 Zinc 2,800 2,498 The pollutant concentrations in the residuals which will be applied to the land shall not exceed the following Ceiling Concentrations (Dry Weight Basis): Parameters mg/kg Arsenic 75 Cadmium 85 Copper 4,300 Lead 840 Mercury 57 Molybdenum 75 Nickel 420 Selenium 100 Zinc 7,500 8. Upon classification of the facility by the Water Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall employ a certified land application/residuals operator to be in responsible charge (ORC) of the land application program. The operator must hold a certificat of the type classification assigned to the land application program by the WPCSOCC. The Permittee must also employ a certified back-up operator of the appropriate type to comply with the conditions of 15A NCAC 8G.0202. 9. Adequate procedures shall be provided to prevent surface runoff from carrying any disposed or stored residuals into any surface waters. 10. Surface applied residuals will be plowed or disced within 24 hours after application on lands with no cover crop established. 11. For areas that are prone to flooding or within the 100 -year flood elevation, residuals may be applied only during periods of dry weather. The residuals must be incorporated into the soil within 24 hours after application. 12. Appropriate measures must be taken to control public access to the land application sites during active site use and for the 12 -month period foIIowing the last residual application event. Such controls may include the posting of signs indicating the activities being conducted at each site. 13. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying pollutants from the residuals application area onto the adjacent property or into any surface waters. 14. Residuals shall not be applied in inclement weather or until 24 hours following a rainfall event of 1i2 - inch or greater in 24 hours. Any emergency residuals disposal measures must first be approved by the Division. 15. Residuals shall not be applied to any land application site that is flooded, frozen or snow-covered. 16. Residuals shall not be applied at rates greater than agronomic rates, unless authorized by the Division. 17. Animals shall not be grazed on an application site for 30 days after residuals application. Application sites that are to be used for grazing shall have fencing that will be used to prevent access after each application. 18. Food crops, feed crops and fiber crops that do not come in contact with the residuals shall not be harvested for 30 days after residuals application. 19. Food crops with harvested parts that touch the residual/soil mixture and are totally above the land surface (ex. tobacco, melons, cucumbers, squash, etc.) shall not be harvested for 14 months after residuals application. 20. Food crops with harvested parts below the surface of the land (root crops such as potatoes, carrots, radishes, etc.) shall not be harvested for 20 months after application of residuals when the residuals remain on the land surface for four months or longer prior to incorporation into the soil. 21. Food crops with harvested parts below the surface of the land shall not be harvested for 38 months after application of residuals when the residuals remain on the land surface for less than 4 months prior to incorporation into the soil. 22. Turf shall not be harvested for 1 year after residuals application. 4 III. MONITORING AND REPORTING REQUIREMENTS Any monitoring (including groundwater, surface water, residuals, soil, or plant tissue analyses) deemed necessary by the Division to insure protection of the environment will be established and an acceptable sampling and reporting schedule shall be followed. 2. Proper records shall be maintained by the Permittee tracking all application activities.
