(A) Brunswick County’s Sewer Use Ordinance shall apply to the treatment standards for the town and county sewer treatment processing, or the following minimum standards, whichever is more restrictive.
(B) In order that the biological treatment process is not subjected to unacceptable levels of toxic wastes and so that the process can function properly to meet
state and federal standards, it shall be unlawful for any person to discharge into the town’s wastewater collection system, waters containing in excess of:
(1) These constituents with these concentrations.
Constituent | Code | Maximum Permissible Concentration |
Constituent | Code | Maximum Permissible Concentration |
Arsenic | AS | 0.1 mg/l |
Boron | B | 10.0 mg/l |
Barium | BA | 0.5 mg/l |
Cadmium | CD | 0.2 mg/l |
Copper | CU | 0.1 mg/l |
Cyanide | CN- | 0.5 mg/l |
Lead | PB | 1.0 mg/l |
Mercury | HG | 0.5 ug/l* |
Nickel | NI | 0.5 mg/l |
Silver | AG | 0.03 mg/l |
Total chromium | CR | 0.5 mg/l |
Vanadium | V | 0.5 mg/l |
Zinc | ZN | 0.5 mg/l |
Chloroform | CHCL3 | 1.0 mg/l |
*ug/l; lug/l = 0.001 mg/l

(2) Having a five-day BOD of more than 1,000 mg/l;
(3) Having a TSS content of more than 1,000 mg/l;
(4) Having a COD of more than 1,500 mg/l;
(5) Having a pH lower than 5.5;
(6) Having a pH higher than 9.5;
(7) Having a temperature higher than 150°F, 65.5°C;
(8) Containing more than 40 mg/l of oil and grease of animal or vegetable origin;
(9) Containing more than 40 mg/l of oil and grease of mineral or petroleum origin;
(10) Containing in excess of 0.02 mg/l total identifiable chlorinated hydrocarbons which cannot be removed by the town’s treatment process;
(11) Containing 1.0 mg/l phenolic compounds which cannot be removed by the town’s treatment process;
(12) Containing any toxic substances or poisonous substances in sufficient quantities to interfere with the biological processes used at the town’s treatment works;
(13) Containing strong iron pickling wastes or concentrated plating solutions unless pretreated in such a way as to comply with all other limitations of § 52.007;
(14) Containing any solid viscous substance, including but not being limited to: ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, bones, feathers, slurry, lime residues, slops, whole blood, fleshings, chemical residues, paint residues, waxes, asphalt, hair, tar, plastics, wood, paunch manure, butcher’s offal, animal viscera, lime or any solid or viscous substances capable of causing obstructions of any kind in either the collection system or at any point in the treatment plant. Also any waste that will not pass through a one-fourth-inch mesh screen or its equivalent in screening ability is not to be discharged into the sanitary sewer collection system, but disposed of by an alternative means;
(15) Containing any liquid waste or other such substance that contains dyes or other color of a character and quantity as to prevent removal by biological processes employed at the treatment plant;
(16) Containing any liquid or other substances that require excessive amounts of chlorine for stabilization in addition to biological treatment. The excess chlorine demand exerted by this waste shall be determined by comparing the chlorine demand of the waste to the average chlorine demand of all other wastes entering the treatment plant;
(17) Of the industrial variety with such a volume that the peak hourly flow exceeds 2.5% of the design flow of the treatment works. In cases where a peak hourly flow of more than 2.5% is discharged, the town may require the discharger to provide holding facilities of sufficient capacity so as to discharge into the collection system at an assigned rate over a specified period of time; or
(18) Of such a nature that will cause contamination of the waste in the collection system, or which may contaminate the treatment plant or the receiving waters of the state, resulting in injury or harm to persons, livestock or aquatic life.
(C) Users in industrial categories subject to effluent guidelines issued under Section 304(b) of the Federal Act which are discharging incompatible pollutants to publicly owned treatment works, are required to adopt best practicable control technology currently available, and defined by the Administrator pursuant to Section 304(b) of the Act. Where the town’s treatment works was designed to and does achieve substantial removal of pollutants other than the four pollutants listed in the definition for compatible pollutants in Section 24-86 (BOD, TSS, pH and fecal coliform bacteria), the Director of Public Works may not require the user to achieve best practicable control technology currently available, since this would lead to an uneconomical duplication of treatment facilities. While the term SUBSTANTIAL REMOVAL is not subject to precise definition, it generally contemplates removals in the order of 80% or greater; minor incidental removals in the order of 10% to 30% are not considered “substantial.” For some industrial categories, it may be necessary to define pretreatment guidelines for problems that may arise as a result of the discharge into the town’s treatment works. However, any adjustments required for particular industrial categories should be considered in connection with the town’s requirements rather than in the national pretreatment standard. Limitations on wastewater strength in this subchapter may be supplemented with more stringent limitations pursuant to § 52.012.
