shall be removed manually.
b. All pump and alarm systems shall be inspected and tested monthly.
(5.)Records Retention:
a. Submittal Of monthly Discharge Monitoring Reports(DMRs)shall not be required except upon demand
by the Division.This section supersedes the requirement for submitting monthly Discharge Monitoring
Reports(DMRs)specified in Part II, Section D(2)of this permit.Even though the submittal of the
monthly monitoring reports to the Division-is suspended,all monitoring requirements-remain.
b. The data will be maintained on site for a period of three years.

noncompliance with the permit.
(6.)Outfall Location:
A visual-review of the outfall location shall be executed twice Each year(one at the time of sampling)to
ensure that no visible solids Or other Obvious"evidence of system nialfiuictioniilg is observed:Any visible
signs of a malfunctioning system shall be documented,and steps taken to correct the problem.
(7.)Permit Renewal:
