Aquatic Pesticides to Surface Waters of the United States for Vector Control, adopted by the

The Monitoring Plan is hereby approved for implementation. We anticipate that, as experience

with implementation of this Monitoring Plan grows, it may become necessary to modify the

Monitoring Plan to make it more effective and efficient.

Please be aware that you are required to submit each calendar year an Annual Report to the

Regional Board by January 31 of the following year, as specified in section C. of Attachment B

of the subject NPDES permit. The first Annual Report is due by January 31, 2005. When

submitting the annual report to the Regional Board per the requirements of this permit, please

include a reference to “Compliance File No. CI-8784 and NPDES No. CAG990004”, which will

assure that the reports are directed to the appropriate file and staff. Also, please submit each

type of report as a separate document. 

If you cease the application of pesticides and the permit is no longer needed, please submit

written notification to the Regional Board so that you will not be billed for future annual fees.
