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 m this permit, including such accelerated or additional monitoring as necessary to determine the nature and impact of the noncomplying discharge.
