§ 21-56. Prohibited discharges.

(a)

An industrial user shall not introduce any pollutants into the treatment works which will pass through or interfere with the operation or performance of the treatment facilities.

(b)

No person shall discharge or cause to be discharged to any of the treatment works any substances, materials, waters, or wastes in such quantities or concentrations which do or are likely to:

(1)

Create a fire or explosion hazard including, but not limited to, gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas;

(2)

Cause corrosive damage or hazard to structures, equipment, or personnel of the wastewater facilities, but in no case discharges with the following properties:

(i)

Having a pH lower than 5.0 or greater than 11.0.

These requirements may be modified for treatment works and treatment facilities designed to accommodate greater ranges;

(3)

Cause obstruction to the flow in sewers, or other interference with the operation of treatment facilities due to accumulation of solid or viscous materials;

(4)

Constitute a rate of discharge or substantial deviation from normal rates of discharge, ("slug discharge"), sufficient to cause interference in the operation and performance of the treatment facilities;

(5)

Contain heat in amounts which are likely to accelerate the biodegradation of wastes, causing the formation of excessive amounts of hydrogen sulfide in the treatment works or inhibit biological activity in the treatment facilities, but in no case shall the discharge of heat cause the temperature in the wastewater sewer to exceed fifty-eight (58) degrees Celsius (one hundred fifty (150) degrees Fahrenheit) or the temperature of the influent to the treatment facilities to exceed forty (40) degrees Celsius (one hundred four (104) degrees Fahrenheit) unless the facilities can accommodate such heat and the town has obtained prior approval from the Virginia Department of Environmental Quality;

(6)

Contain more than one hundred (100) milligrams per liter of nonbiodegradable oils of mineral or petroleum origin;

(7)

Contain floatable oils, fat, or grease;

(8)

Contain noxious, malodorous gas or substance which is present in quantities that create a public nuisance or a hazard to human or animal life;

(9)

Contain radioactive wastes in harmful quantities as defined by applicable state and federal regulations;

(10)

Contain any garbage that has not been properly shredded;

(11)

Contain any odor or color producing substances exceeding concentration limits which may be established by the manager for purposes of meeting the Town's Virginia Pollution Discharge Elimination System (VPDES) permit.

(c)

If, in establishing discharge restrictions, discharge limits, or pretreatment standards pursuant to this article, the manager establishes concentration limits to be met by a user, the manager in lieu of concentration limits, may establish mass limits of comparable stringency for an individual user at the request of such user. Upon approval by the State such limits should become pretreatment standards.
