§ 340-30. Discharges subject to regulations.

No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Director that such wastes can harm the wastewater facility or equipment, have an adverse affect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming an opinion as to the acceptability of these wastes, the Director will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature and capacity of the wastewater facility, degree of treatability of wastes in the wastewater treatment works and other pertinent factors. The substances which must be considered include but are not limited to the following:

A. 

Any liquid or vapor having a temperature higher than 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32° and 150°.

B. 

Any water or waste containing fats, grease, wax, or oils, whether emulsified or not, in excess of 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32° and 150°.

C. 

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 Director.

D. 

Any waters or wastes containing strong-acid iron-pickling wastes, or concentrated plating solutions cannot be discharged to the wastewater facility unless completely neutralized and approved by the Director for discharge.

E. 

Any waters or wastes containing reducing substances of an organic or inorganic nature, toxic or nontoxic, which exert an immediate chlorine demand shall not 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.

F. 

Any waters or wastes containing phenols or other taste or odor-producing substances cannot be discharged to the wastewater facility in concentrations exceeding limits established by the Director. Dilution shall not be used to decrease the concentrations.

G. 

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

H. 

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

I. 

Materials which exert or cause:

(1) 

Unusual concentrations of inert suspended solids (such as, but not limited to, fuller's earth, lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate).

(2) 

Excessive discoloration (such as, but not limited to, animal blood dye wastes, and vegetable tanning solutions).

(3) 

Unusual chemical oxygen demand, or biochemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment works.

(4) 

Slugs or shocks constituting an unusual volume of flow or concentration of wastes which will disturb the normal functioning of the wastewater facility.

J. 

Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment works employed, or are amenable to treatment only to such degree that the effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
