Any constituent not listed herein may be added by regulation or other prohibition promulgated by the Director based on results of technical determinations, the actions of regulatory agencies, the projected impact of the constituent upon the wastewater system, and the capacity of wastewater treatment facilities to accommodate such constituent.
B. No person, whether or not a permittee, shall discharge or cause to be discharged directly or indirectly into a sewer lateral, or into the wastewater system or facilities, the following:
1. Any gasoline, benzene, naphtha, solvent, fuel oil or any liquid, solid or gas that would cause or tend to cause flammable or explosive conditions to result in the wastewater system.
2. Any matter containing toxic or poisonous solids, liquids or gases in such quantities that, alone or in combination with other substances, may create a health hazard for humans, animals or the local environment; interfere detrimentally with wastewater treatment processes; cause a public nuisance; or cause any hazardous condition to occur in the wastewater system.
3. Any matter having a pH lower than 5.0 or greater than 11.0 or having any corrosive or detrimental characteristic that may cause injury to wastewater treatment or maintenance personnel or may cause damage to structures, equipment or other physical facilities of the wastewater system.
4. Any solids or viscous substances or other matter of such quality, size or quantity that they may cause obstruction to flow in the sewer or be detrimental to proper wastewater treatment plant operations. These objectionable substances include, but are not limited to, asphalt, dead animals, offal, ashes, sand, mud, straw, industrial process shavings, metal, glass, rags, feathers, tar, wood, whole blood, paunch manure, bones, hair and fleshings, entrails, fatty acids, grease and oil, paper dishes, paper cups, milk containers, or other similar paper products, either whole or ground.

6. Any matter having a temperature higher than 150 degrees Fahrenheit (65 degrees Celsius), or at a temperature which causes the influent to the waste treatment plant to exceed 104 degrees Fahrenheit (40 degrees Celsius).
7. Any matter containing more than 500 mg/l of oil or grease.
8. Any strongly odorous matter or matter tending to create odors.
9. Any matter containing over 1.0 mg/l of dissolved sulfides.
10. Any matter with a pH high enough to cause alkaline incrustations on sewer walls.
11. Any matter promoting or causing the promotion of toxic gases.
12. Any matter requiring an excessive quantity of chlorine or other chemical compound used for disinfection purposes.
13. Any excessive amounts of deionized water, steam condensate, distilled water or single-pass cooling water.
14. Any radioactive matter, except:
a. When the person is authorized to use radioactive materials by the State Department of Health or other governmental agency empowered to regulate the use of radioactive materials; and
b. When the matter is discharged in strict conformity with current California Radiation Control Regulations (California Administrative Code Title 17), and the Nuclear Regulatory Commission regulations and recommendations for safe disposal; and

15. Any matter producing excessive discoloration of the wastewater treatment plant effluent.
16. Any toxic materials including, but not limited to, all heavy metals, cyanide, phenols, chlorinated hydrocarbons and other organic compounds, unless limited to that concentration which complies with all local, state and federal discharge limitations, and which does not interfere with the operation of the wastewater facilities.
17. Any substance, liquid, gas or solid waste which would cause a public nuisance or hazard to life, or would be deleterious to the operation of wastewater facilities or to the waters receiving the discharge of the wastewater facilities.
18. Any cesspool or septic tank wastes. (Ord. 2466 § 7, 1991).
