Dear Bruce A. Humble:

The Division of Water Resources (Division) received your sludge survey information on
November 30, 2022. With the survey results, you requested an extension of the sludge survey
requirement for the upper lagoon (Lagoon #1) at the Bruce Humble Farm facility. Due to the
amount of treatment volume available, and the rate of sludge accumulation for the lagoon, the
Division agrees that a sludge survey is not needed until December 31, 2027.

The next sludge survey for the upper lagoon (Lagoon #1) at Bruce Humble Farm should be
performed before December 31, 2027. Please retain this letter and keep it with your farm records
for reference.

Please call me at [phone] if you have any questions.

Sincerely,
M iressaD. Garoma
