Chapter 13.04 — SEWAGE DISPOSAL

A.

The discharge of certain materials to on-site wastewater disposal systems, or the construction and maintenance of on-site wastewater disposal systems which are defective or substandard in operation, may result in adverse impacts on human health or the physical environment, including but not limited to: pollution of soil and groundwater, disruption of proper system functioning, disruption of treatment plant functioning, creation of a health hazard to septic service personnel, or creation of a hazard where septic tank sludge is discharged.

B.

It is the intent of this chapter to prevent such adverse impacts by prohibiting the discharge of hazardous or deleterious materials to on-site wastewater disposal systems, to prohibit the improper disposal of contaminated septic tank sludge, and to assure that all on-site wastewater disposal systems within the town are constructed and operated in a safe, healthful and environmentally responsible manner.

C.

Evaluation of the Observed Operating Performance of On-Site Wastewater Treatment and Disposal Systems at the Time of Building Permit Application Submittal.

No person shall obtain town approval of a building permit application requiring a plan check for any property in the town upon which a septic tank and disposal drainfield, also known as an on-site wastewater treatment and disposal system, has been constructed and/or is operating without first providing a septic system evaluation report to the town. Such septic system evaluation report shall be completed by a town- licensed evaluator. The septic system evaluation report shall provide evidence that the observed operational performance of the on-site wastewater treatment and disposal system is in substantial compliance with town regulations including Section 13.04.230.

As used in this section, evidence of substantial compliance shall be a current on-site wastewater treatment and disposal system evaluation performed by a qualified person possessing such authority as confirmed by Chapter 5.14 of this code. Evidence of a current on-site wastewater treatment and disposal system evaluation shall be a current operating permit.
