Industrial General Permit Order

encouraged to utilize BMPs that infiltrate or reuse storm water where
feasible.

iii. Treatment Control BMPs

This is the implementation of one or more mechanical, chemical,
biologic, or any other treatment technology that will meet the
treatment design standard.

iv. Other Advanced BMPs

Any additional BMPs not described in subsections b.i through iii
above that are necessary to meet the effluent limitations of this
General Permit.

3. Temporary Suspension of Industrial Activities

For facilities that plan to temporarily suspend industrial activities for ten (10)
or more consecutive calendar days during a reporting year, the Discharger
may also suspend monitoring if it is infeasible to conduct monitoring while
industrial activities are suspended (e.g., the facility is not staffed, or the
facility is remote or inaccessible) and the facility has been stabilized. The
Discharger shall include in the SWPPP the BMPs necessary to achieve
compliance with this General Permit during the temporary suspension of the
industrial activity. Once all necessary BMPs have been implemented to
stabilize the facility, the Discharger is not required to:

a. Perform monthly visual observations (Section XI.A.1.a.); or,

b. Perform sampling and analysis (Section XI.B.) if it is infeasible to do so
(e.g. facility is remotely located).

The Discharger shall upload via SMARTS (7) seven calendar days prior to
the planned temporary suspension of industrial activities:

a. SWPPP revisions specifically addressing the facility stabilization BMPs;

b. The justification for why monitoring is infeasible at the facility during the
period of temporary suspension of industrial activities;

c. The date the facility is fully stabilized for temporary suspension of
industrial activities; and,

d. The projected date that industrial activities will resume at the facility.
