Good housekeeping measures as outlined in the facility’s SWPPP, and in
accordance with Part 2.1.1.2, such as: ensure materials are properly labeled, clean
up trash, debris and other materials;
Ensure the site is secured, such as locking entrance gates; and
Material stockpiles shall be protected from erosion.
If circumstances change and the facility becomes active and/or staffed, this exemption no
longer applies and the permittee shall immediately begin complying with the applicable
benchmark monitoring requirements as if the facility were in the first year of permit
coverage, including the wet season visual assessment requirements; and
ADEQ retains the authority to revoke this exemption and/or the monitoring waiver where it
is determined that the discharge causes, has a reasonable potential to cause, or contribute
to an exceedance of an applicable water quality standard, including designated uses.
Subject to the two conditions above, if the facility is inactive and unstaffed, the permittee is
waived from the requirement to conduct wet season visual assessments and benchmark
monitoring. The quarterly routine facility inspections are reduced to one routine facility
inspection and one CFI each calendar year. These inspections shall be conducted in the
opposing wet seasons and at least three months apart. The permittee shall also inspect the site
whenever there is a reasonable expectation that severe weather or natural disasters may have
damaged control measures or increased discharges.
