Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided. V . INSPECTIONS 1. The Permittee or his designee shall inspect the residuals storage, transport, and treatment facilities to prevent malfunctions and deterioration, operator errors and discharges which may cause or lead to the release of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall maintain an inspection log or summary including at least the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee. This log of inspections shall be maintained by the Permittee for a period of five years from the date of the inspection and shall be made available to the Division of Environmental Management or other permitting authority, upon request. 2. Any duly authorized officer, employee, or representative of the Division of Environmental Management may, upon presentation of credentials, enter and inspect any property, premises or place on or related to the treatment site or facility at any reasonable time for the purpose of determining compliance with this permit; may inspect or copy any records that must be kept under the terms and conditions of this permit; and may obtain samples of groundwater, surface water, or leachate. V1. GENERAL CONDITIONS 1. This permit shall become voidable unless the distribution activities are carried out in accordance with the conditions of this permit, the supporting materials, and in the manner approved by this Division. 2. This permit is effective only with respect to the nature and volume of residuals described in the application and other supporting data. 3. This permit is not automatically transferable.

(1) Activated Carbon Beds. A phlyslcaVchemica[ method for reducing soluble organic malarial from wastewater effluert; The column -type beds used In this method will have a flow rate varying from two to eight gallons per minute per square fool and may be either uptlow or downflow carbon beds. Carbon may or may not be regenerated on the waslewaler treatment plant she; (2) Aerated Lagoons. A basin In which all solids are maintained in suspension and by which biological oxldallon or organic matter is reduced through artificially accelerated transfer of oxygen on a clow -through basis; (3) Aeration. A process of bringing about Inllmate contact between air or blah purity oxygen In a liquid by spraying, agitation or dlfiuslon;(3a) Extended Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 houm- (4) Agricuhuralfy managed site. Any site on which a crop is produced, managed, and harvested (Crop Includes grasses, grains, frees, etc.); (5) Air Stripping. A process by which the ammonium ion Is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the atmosphere by physical means; or other slmllar processes which remove petroleum products such as benzene, toluene, and xylene; (6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volallllze and oxidize the absorbed Impurhles; 'i Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent limits; Centrifuge. A mechanfcai device In which contrffugaf force fs used to separate solids from liquids or to separate liquids of different densGlas; Chemical Additlon Systems- The addhion of dtomlcal(s) to wastewater ad an applkztlon point for purposes of improving solids removal, pH adjustment• i lkalfnity control, etc.; the tapablhty to experiment with ddferem chemicals and ddlerent appiicalton points to achieve a spech1c result wilt be considered one system; the capabllfty to add chemkal(s) to dual units wilt be rated as one system; capabiftty to add a chemkal at a dilferent application points for different purposes wllf result In the systems being rated as separate systems; (10) Chemical Sludge Condltlordng. The addhion of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to hs application to a dewatering device; (11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater contafning Irwganlc, non-toxlc materials from sand, gravel, crushed stone or other slmilar operations. Such cysiorns shall carry a maximum of Iwo points regardless of pumping facllitles or any other appurtenances; (12) Combined Aomoval of Carbonaceous 600 and Nitrogenous Removai by Nitrifica(Ion- A shale stage system required to achieve permit effluent limits on 500 ar-1 amm.,.,t, nhronnn whNn the same bioloo;cal reactor.
