B.  A BES discharge permit or authorization request must be submitted and approved before non-routine or one-time discharges of materials except for those discharges that are allowed under Section 17.39.030.

C.  A discharge request must be submitted and BES must approve or deny the permit before continuous or routine discharge occurs of materials other than stormwater that are not allowed under Section 17.39.030.  A discharger must apply for a BES discharge permit or authorization when required by BES either at the time of development application or at the time of discovery of a discharge meeting the criteria of Subsection 17.39.060 A. 

D.  The discharger must allow site inspections by BES to verify site conditions or submit additional information, reports and plans as part of the DA or BES discharge permit request, such as:

1.  A Stormwater Pollution Control Plan (SWPCP), which describes measures to eliminate, reduce and control the level of pollutants in discharges;

2.  An Accidental Spill Prevention Plan (ASPP), which documents facility or discharger-specific spill response procedures and describes measures to prevent the release of prohibited or deleterious materials to the City storm sewer and drainage system;

3.  A Best Management Practices (BMP) Plan which describes actions to reduce or eliminates pollutants and hydrologic impacts associated with a discharge; or

4.  Monitoring data to characterize the types and loads of pollutants in the discharges.

E.  The Director shall provide the discharger written notice of approval or denial of the request to discharge and information on how to request further administrative review of the decision.

F.  Any new or potential discharger identified through the City’s development review process shall undergo a source control review.  Such review shall identify any site controls, City permit, or DA submittals needed to approve and accept any new discharge.
