2. Any matter which is chemically or physically stable for at least five days at twenty degrees centigrade, or which would form a deposit or obstruction or damage or reduce the capacity of the sewer into which it was placed;
3. Flammable, explosive or poisonous liquids, gases or solids or any matter which, after entrance into a sewer, might reasonably be expected to form in any way such flammable, explosive or poisonous liquids, gases or solids;
4. Matter of any nature at a temperature above one hundred fifty degrees Fahrenheit;
5. Liquid matter of any nature containing suspended solids in excess of two hundred fifty parts per million;
6. Matter of any nature containing a five-day biochemical oxygen demand (BOD) in excess of two hundred fifty parts per million;
7. Animal or vegetable greases, oils or matter containing animal or vegetable grease or oil of any nature in excess of fifty parts per million, or any petroleum products;
8. Liquid matter with a hydrogen ion concentration below 6.0 or above 9.0;
9. Substances having a strong odor, unpleasant odor;
10. Substances which can produce a toxic vapor, including, but not limited to, chlorinated hydrocarbons;
11. Food waste which has not been properly shredded so that one hundred percent will pass a three-eighths-inch sieve and seventy-five percent pass a one-fourth-inch sieve. Persons engaged in the retail sale of raw produce shall be limited to one grinder having a prime mover not exceeding five horsepower for the processing of raw produce waste;
12. Waste matter containing daily maximum metal concentrations in excess of state and/or federal laws and regulations;
13. Radioactive waste; and
14. Hazardous wastes concentrations in excess of state and/or federal laws and regulations;
15. Any matter which, in the opinion of the director of public works, might interfere with the satisfactory operation of any treatment plants or any portion of the sewer system.
B. Discharge of substances prohibited under subsection A of this section shall be referred to as “excess pollutant discharge.” In the event that sewage or other matter having or exceeding the above characteristics is discharged into the sewer system, in addition to other remedies, including criminal prosecution, the public works director shall issue a cease and desist order. Further, the public works director shall investigate the circumstances of such excess pollutant discharges or sewer system blockages and estimate the cost of correction and/or treatment of the discharges during the time the discharges have occurred, and the cost of correction or treatment of the discharges shall be added to the sewer charges of the customer discharging the sewage or other matter. The costs shall be collected in the same manner and procedures as all other sewer rates and charges, including lien provisions, and shall be subject to adjustment in accordance with the utility billing supervisor’s procedure.
C. In the event that the public works director finds that excess pollutant discharges of liquids containing suspended solids in excess of two hundred fifty parts per million or matter having a five-day BOD in excess of two hundred fifty parts per million or fats, oils and grease in excess of fifty parts per million may be continued without impairing proper operation of the Everett municipal sewer system, the public works director may issue an excess pollutant discharge permit and establish charges therefor. The permit shall be revocable at any time by the public works director upon finding that continued discharge of sewage exceeding the above standards will impair operation of the Everett sewer system at the time of sewer connection application. All applicants intending to operate any industrial or manufacturing operations shall submit data concerning type of wastewater discharges and the public works director shall consider issuance of an excess pollutant discharge permit at that time.
D. Correction of sewer system blockages shall be charged on a time and material basis. The city council shall by resolution establish the charges for excess pollutant discharges on the basis of an annual analysis of sewer collection and treatment costs. (Ord. 1506-88 § 17, 1988.)
