3. Definitions

a. The " doily overage" discharge means the total discharge by weight during a coiendar month divided by the number of days in the month that the production or commercial facility was operating.

Where less than daily sampling is required by this permit, the daily overage discharge shall be determined by the summotion of oil the measured daily discharges by weight divided by the number of days sampled during the calendar mmth when the measurements were made.

! b. The " daily maximum" discharge means the total discharge by weight during my calendar cby.

c. The " doily overage" concentration means the crithmetic average (weighted by flow value) of all the daily determinations of concentration made during a calendor month. Daily determinations of concentration mode using a composite sample shall be the concentration of the composite sample. When grab samples are used, the daily determination of concentration shall be the crithmetic overage (weighted by flow value) of all the sample collected during that calendar day.

1. Change in Discharge All discharges authorized herein shall be consistent with the terms md conditions of this permit. The discharge of any pollutant identified in this permit more frequeny than or at a level in excess of that authorized shall constitute _ s'olation of the permit. Any anticipated facility expansions, production increases, or process modifications which will result in new, different, or increased discharges or pollutants must be reported by submission of a new NPDES application or, if such changes will not violate the effluent limitations specified in this permit, by notice to the EPO of such changes. Following such notice, the permit may be modified to specify and limit any pollutants not previously limited.

2. Noncompliance Notification i

L If, for any reason, the permittee does not comply with or will be unable to comply with any daily maximum effluent limitation specified in this permit, the permittee shall provide the Water Quality Control Section of EPD with the following'information, in writing, within five (5) days of becoming aware of such condition:

a. A description of the discharge md cause of noncompliance; and

b. The period of noncompliance, including exact cbtes and times; or, if not correc ted, the anticipated time the noncompliance is expected to continue, and steps being token to reduce, eliminate and prevent recurrence of the noncomplying discharge.

3. Facilities Operation The permittee shall at all times maintain in good working order and operate as ef ficientiv as possible all treatment or control facilities or systems installed or used by the permittee to achieve compliance with the terms and conditions of this permit.

4. Adverse Impact The permittee shall take all reasonable steps to minimize any adverse impact to navigable waters resulting from noncompliance with any effluent limitations specified in this per mit, including such accelerated or additional monitoring as necessary to determine the nature and impact of the noncomplying discharge.
