Waste discharges shall not exceed the following daily maximum concentration
limitations:
a. five day biochemical oxygen
demand-maximum concentration allowed in accordance with Secondary Treatment
Effluent Standards (LAC 33:IX.711);
b. total suspended solids-maximum
concentration allowed in accordance with Secondary Treatment Effluent Standards

results in a violation of water quality standards, the department reserves the
right to impose more stringent requirements.
C. Service Stations

4. To the greatest extent
possible, spills on external service areas shall be cleaned up using dry
methods.
5. Discharges and runoff
from internal and external service areas and diked bulk storage areas shall
comply with a maximum oil and grease concentration limitation of 20
mg/L.
6. If sanitary wastes are
combined with discharges from internal service areas, the combined wastes shall
additionally comply with the provisions set forth in LAC
33:IX.709.B.1.

Reserved
H. Construction Sites
1. This category includes all construction
sites under the control of a single party in which the disturbed area is larger

required.
2. All wastewaters,
including stormwater runoff, leaving the site boundaries shall be controlled so
as to comply with the following limitations:
a. a maximum oil and grease concentration of
15 mg/L;
b. until such time as
disturbed areas have been revegetated, a settleable solids concentration of 1.0
mL/L.
