§ 13.12.050. Prohibited waste discharge.

No person may discharge or cause to be discharged any of the following described liquids or wastes to any public sewers:

A.

Any pollutant with a closed-cup flashpoint of less than one hundred forty degrees Fahrenheit or sixty degrees centigrade or which are injurious in any other way to the wastewater facility or to the operation of the wastewater facility. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, formaldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, sulfides, any other solvent, and any other substances which the city, the New Mexico Environment Department or U.S. EPA has notified the user is a fire hazard or a hazard to the wastewater facility;

B.

Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any wastewater facility, to constitute a hazard to humans or animals, to create a public nuisance, or to create any hazard in the receiving waters of the wastewater treatment works, including but not limited to cyanides in excess of 0.2 mg/l as CN in the wastes as discharged to the public sewer;

C.

Any herbicides or pesticides, or other toxic refractory organic chemicals;

D.

Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of a wastewater facility;

E.

Solid or viscous substances in quantities or of a size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facility such as, but not limited to, ashes, cinders, sand, mud, straw, metal, glass, rags, feathers, tar, residues from refining or processing of fuel or lubricating oil, plastics, wood, unground garbage, whole blood, paunch manure, hair and flesh, entrails, and paper or plastic dishes, cups and milk containers, either whole or by garbage grinders;

F.

Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (sixty-five degrees centigrade);

G.

Any water or waste containing fats, grease, wax or oils, whether emulsified or not, in excess of one hundred mg/l or containing substances which may solidify or become viscous at temperatures between thirty-two and one hundred fifty degrees Fahrenheit (between zero and sixty-five degrees centigrade);

H.

Any garbage that has not been properly shredded. The installation and operation of any garbage grinder larger than those normally manufactured and sold for residential and noncommercial use will not be installed without specific review and approval by the city manager;

I.

Any radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by the city manager in compliance with applicable state and federal regulations;

J.

Any waters or wastes having a pH in excess of 9.5;

K.

Petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin or any substance which may cause an interference or pass-through;

L.

Any water or waste containing total residual chlorine in excess of two mg/l;

M.

Any water or waste containing ammonia (as nitrogen) in excess of sixty-five mg/l and/or total kjeldahl nitrogen (TKN) in excess of one hundred mg/l;

N.

Any waters or wastes containing readily reducing oxidizable substances of an organic or inorganic nature, toxic or nontoxic, which exert an immediate chlorine demand cannot be discharged into the wastewater facility if discharge of such agents will prevent the achievement of an adequate chlorine residual in the effluent of the wastewater treatment works;

O.

Any amount of the following contaminants in excess of the scale as shown below:

Contaminant	Daily Maximum Discharge Concentration (mg/l)
Aluminum	5.0
Arsenic	0.1
Asbestos	7.0 million fibers/liter
Barium	2.0
