The Board of Supervisors finds that discharge of certain materials to individual wastewater disposal systems may result in pollution of groundwater, disruption of proper system functioning, disruption of treatment plant functioning, or creation of a hazard where septic tank sludge is discharged. It is the intent of this article to prevent these adverse impacts by prohibiting the discharge of deleterious materials to individual sewage disposal systems, and to prohibit the improper disposal of contaminated septic tank sludge.
(Ord. 3818 § 2, 1987; Ord. 5310 § 8, 2019)
"Deleterious material"
means the following substances or combination of substances:
(A) 
"Hazardous materials" or "hazardous substances,"
as defined in SCCC § 7.100.040;
(B) 
Substance or combination of substances which inhibit the normal biological or physical treatment processes in the septic tank or other parts of the wastewater disposal system; or
(C) 
Substance or combination of substances which interfere with the process or efficiency of any wastewater treatment plant where the septic tank sludge is discharged.
Deleterious material include but is not limited to: pesticides, organic solvents, gasoline, paints, caustic chemicals, motor oil, degreasers, paint thinner, wood preservatives, paint strippers, septic tank cleaners containing organic solvents, unmixed photographic chemicals, and fiberglass resins.
(Ord. 3818 § 2, 1987; Ord. 5310 § 8, 2019)
It is unlawful for any person to discharge to an individual sewage disposal system any deleterious material unless prior authorization to do so has been granted by the Health Officer. Authorization may only be granted where such discharges would not cause adverse impacts, as defined in SCCC § 7.42.100.
(Ord. 3818 § 2, 1987; Ord. 5310 § 8, 2019)
Discharge of septic tank sludge containing deleterious material(s) shall only be to a site or facility specifically approved by the Health Officer for disposal of such contaminated sludge.
