' CONSTRUCTION DEWATERING
OPERATIONS IN COLORADO
GENERAL PERMIT FOR DISCHARGE
RATIONALE
COLORADO DISCHARGE PERMIT NUMBER: COG-070000
Excavation dewatering in conjunction with construction activities often results
in temporary discharges to waters of the United States. These discharges are
subject to the requirements 25-8-101 et. seq. , CRS, 1973 as amended. Obtaining
a discharge permit may be essential to the construction activity and its
scheduling. Administrative delays in the issuance of a permit might
significantly impact the timing and cost of a project. Situations have arisen
in the past where permit processing delays, or anticipation of delays, have
resulted in applicants discharging prior to receipt of authorization. The
intent of a General Permit for construction dewatering is to facilitate the
scheduling of these activities by reducing the administrative delays in their
authorization, to establish a uniform criteria for management practices and
effluent limitations for discharges from these activities, and promote a
consistent permitting and enforcement posture with respect to these activities.
The General Permit regulations provide for the issuance of General Permits
where covered facilities:
1. are involved in substantially the same type of operations;
2. discharge the same type of waste;
3. require the same effluent limitations or operating conditions;
4. require similar monitoring; and,
5. are more appropriately controlled under a General permit than
individual permits.
Applicability
This category, "construction dewatering", will include dewatering from building
construction, general construction, highway, bridge and tunnel construction,
among others considered appropriate by the Division. The dewatering associated
with this construction activity will be relatively short-term and will not
include any pollutants other than those which normal physical disturbance,
pumping, or construction activity might create. Overburden removal is not
considered a. construction activity. The Division retains the authority to
individually permit facilities determined to be in noncompliance with the
conditions of this General Permit or not qualifying for a General Permit. (see
PART II, B. 5, page 13 of the permit)
