B.

Exceptions to Illicit Discharges. The following categories of non-stormwater discharges shall not be considered illicit discharges under this ordinance unless the director determines that the type of discharge, whether singly or in combination with others, is causing or is likely to cause significant pollution of surface water or groundwater, or is causing or contributing to a violation of the County's NPDES stormwater permit:

1.

Potable water; provided the water is not chlorinated in excess of 0.1 ppm total chlorine and will have no detectable total chlorine residual upon reaching waters of the state or United States, is pH-adjusted, and the volume and velocity are controlled to prevent erosion and re-suspension of sediments in the stormwater drainage facility and in the receiving water

2.

Dechlorinated or debrominated swimming pool discharges, provided that they are dechlorinated to a concentration of 0.1 ppm or less or debrominated to a concentration of 0.01 ppm or less, and are pH-adjusted and re-oxygenated if necessary, and the volume and velocity are controlled to prevent erosion and re-suspension of sediments in the stormwater drainage facility and in the receiving water. Discharge of swimming pool backwash water is prohibited.

3.

Air conditioning condensation.

4.

Uncontaminated water from crawl space pumps or footing or foundation drains.

5.

Uncontaminated pumped ground water.

6.

Natural uncontaminated surface water or ground water.

7.

Uncontaminated roof runoff water.

8.

Street and sidewalk wash water, water used to control dust, and external building wash down that does not use detergents, provided the discharge is minimized.

9.

Non-stormwater discharges covered by another NPDES or State Waste Discharge Permit.

10.

Discharges from emergency fire fighting activities.

11.

Discharges containing water tracing dyes used specifically for the purpose of drainage system or pollution investigations. Any persons conducting dye tests, other than county departments, must provide verbal notification to the director prior to initiation of the dye test.

12.

A person employing properly designed, constructed, implemented, and maintained BMPs and carrying out AKART to prevent pollution of stormwater is considered to be in compliance with sub-section 15.07.060.A above.

C.

Reporting Illicit Discharges. A person must report to the director any spill, release, dumping, or other situation that constitutes an illicit discharge to a storm drainage facility as described in Section 15.07.060.A at the earliest possible time, but in any case within twenty-four hours of discovery. This reporting requirement is in addition to, and does not replace, any other reporting requirements under federal, state, or local laws.

D.

Prohibition of Illicit Connections.

1.

Prohibition of illicit connections. The construction, use, maintenance, or continued existence of an illicit connection to any municipal storm drainage facility is prohibited. This prohibition expressly includes, without limitation, connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection, except for connections conveying discharges listed in Section 15.07.060.B above provided the conditions are met.

2.

Investigation of illicit connections. When the director has reason to believe that an illicit connection exists, the director may conduct an investigation using any and all appropriate methods, including, but not limited to, discharge sample collection and analysis, dye testing, smoke testing, and video methods and recover the costs from the property owner and/or responsible party in an enforcement proceeding.

3.

Exceptions. The director may allow connection to a municipal storm drainage facility, through written authorization, on a case by case basis. Special conditions may be required by the director as part of such an authorization to connect.
