Part I
A. EFFLUENT LIMITATIONS AND MONITORING
				REQUIREMENTS.
1. SHORT TERM PROJECTS.
The following types of short term projects (14 consecutive
				  calendar days or less in duration) are authorized under this permit:
a. Emergency repairs;
b. Dewatering projects. Dewatering projects
				shall be managed to control the volume and velocity of the discharge, including
				peak flow rates and total volume, to minimize erosion at outlets and to
				minimize downstream channel and stream bank erosion;
c. Utility work and repairs in areas of known
				contamination;
d. Tank placement or
				removal in areas of known contamination;
e. Pilot studies or pilot tests, including
				aquifer tests; and
f. New well
				construction discharges of groundwater.
Effluent limits for short term projects correspond to the
				  type of contamination at the project site and are given in Tables A 3 through A
				  6 below. The sampling frequency for these projects shall be once per discharge.
				  Discharge monitoring reports for these projects are not required to be
				  submitted to the department, but shall be retained by the owner for a period of
				  at least three years from the completion date of the project.
Owners shall notify the department's regional office in
				  writing within 14 days of the completion of the project discharge. The
				  notification shall include the owner's name and address, the type of discharge
				  that occurred, the physical location of the project work, and the receiving
				  stream. If the discharge is to a municipal separate storm sewer system (MS4),
				  the owner shall also notify the MS4 owner within 14 days of the completion of
				  the discharge.
