§ 14-68. Prohibited wastes.

No person shall discharge or cause to be discharged into any portion of the sewerage system, directly or indirectly, any wastes which may violate any law or governmental regulation or have an adverse or harmful effect on the sewerage system, maintenance personnel, wastewater treatment plant personnel, processes, or equipment, treatment plant effluent quality, sludge quality, public or private property, or which may otherwise endanger the public, the local environment or create a nuisance. Discharges of the following are prohibited:

(a)

Any gasoline, benzene, naphtha, solvent, fuel oil or any liquid, solid, or gas that may cause flammable or explosive conditions, including, but not limited to, waste streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees centigrade using test methods specified in 40 CFR 261.21;

(b)

Any toxic or poisonous solids, liquids or gases in such quantities that, alone or in combination with other wastewater constituents, may interfere with the sewage treatment process or sludge disposal, cause acute worker health and safety problems, materially increase the cost of treatment, or constitute a hazard to any beneficial stream use, including recreation, ascribed to the receiving waters of the effluent from the sewage treatment plant;

(c)

Any waste having a pH in violation of requirements as provided on 40 CFR Part 403 or having any detrimental characteristics that may cause injury or damage to persons or property;

(d)

Any solids or viscous substances that may cause obstruction to flow or be detrimental to sewerage system operations. These objectionable substances include, but are not limited to, asphalt, dead animals, offal, ashes, sand, mud, straw, industrial process shavings, metals, glass, rags, feathers, tar, plastics, wood, whole blood, paunch manure, bones, hair and fleshing, entrails, paper dishes, paper cups, milk containers, or other similar paper products, either whole or ground;

(e)

Any significant quantities of unpolluted water such as rainwater, stormwater, groundwater, street drainage, yard drainage, water from yard fountains, pond or lawn sprays;

(f)

Any water added for the purpose of diluting wastes which would otherwise exceed applicable maximum concentration limitations for any wastewater constituent;

(g)

Any petroleum or mineral-based oils (non-saponifiable) and/or any animal or vegetable-based oils, fats, or greases which in excess concentrations would tend to cause interference, pass through, or adverse effects on the sewerage system, as determined by the owners of the sewer systems and treatment facilities;

(h)

Any wastes with excessively high BOD, COD, or decomposable organic content or any significant quantities of wastewater with a COD or BOD ratio exceeding six to one;

(i)

Any strongly odorous wastes or waste tending to create odors;

(j)

Any waste containing dissolved sulfides in amounts which would be hazardous, cause damage to the sewerage system, or create a public nuisance;

(k)

Any substance promoting or causing the promotion of toxic gases;

(l)

Any wastes that will increase the temperature of the treatment plant influent to greater than 104°(F) 40°(C);

(m)

Any wastes requiring the introduction of an excessive quantity of chlorine or any other compound for sewage treatment purposes;

(n)

Any excessive amounts of deionized water, distilled water, steam condensate, heating and/or air conditioning condensate or cooling water, and discharges from heat pumps;

(o)

Any waste producing excessive discoloration of wastewater or treatment plant influent;

(p)

Any waste containing substances that may precipitate, solidify, or become viscous at temperatures between 50°(F) 10°(C) and 100°(F) 38°(C);

(q)

Any significant quantities of solid waste material that is not ground sufficiently to pass through a three-eighths-inch screen;

(r)

Any excessive quantity of blown-down or bleed water from cooling towers or other evaporative coolers exceeding one-third of the makeup water;

(s)

Any significant quantities of single pass cooling water;

(t)

Any quantities of radioactive material wastes which are in violations of applicable local, state, and federal regulations;

(u)

Any significant quantities of inorganic material;

(v)

Any discharge of any pollutant release at a flow rate and/or pollutant concentration that would result in interference, cause adverse effects or pass through at the treatment plant;

(w)

Any discharge not in compliance with all standards as set forth in 40 CFR Chapter 1, Subchapter N, Parts 401-471 (National Categorical Standards);

(x)

Any significant quantity of toxic organic (TO) which exceeds 2.13 mg/l, or in which any one toxic organic compound exceeds 1.0 mg/l, or in which the BTEX (Benzene, Toluene, Ethylbenzene and Xylene) concentration exceeds 1.0 mg/l;

(y)

Concentrations of any of the following constituents exceed the particular limitations set forth by HRSD, the City of Franklin, and the Town of Smithfield:

Arsenic

Cadmium

Chromium, total

Copper

Cyanide

Lead

Mercury

Nickel

Phenolic compounds

Silver

Zinc

Oil and grease

(z)

Any other wastes prohibited by the Hampton Roads Sanitation District, or the City of Franklin, and the Town of Smithfield. (5-21-09.)
