On December 8, 1999, Phase II of the National Pollutant Discharge Elimination System (NPDES) stormwater permit program, was published in the Federal Register. The NPDES program, as authorized by the 1972 amendments to the Clean Water Act, controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Phase II of NPDES stormwater program requires permit coverage for stormwater discharges from regulated small Municipal Separate Storm Sewer Systems (MS4s) and for small construction activity that results in the disturbance of one acre or more. This Federal regulation went into effect March 10, 2003. In response to Phase II of NPDES, the Indiana Department of Environmental Management (IDEM) enacted Rule 13 (327 IAC 15-13) to meet the Federal guidelines set for MS4s, and revised Rule 5 (327 IAC 15-5) to cover all construction sites one acre or more. Under State and Federal regulations, the City is required to establish a regulatory mechanism for regulating stormwater quality management. In December 2021, IDEM replaced 327 IAC 15-5 (Rule 5) with an updated Construction Stormwater General Permit (CSGP) and 327 IAC 15-13 (Rule 13) with an updated MS4 General Permit (MS4GP).

The degree of protection required by this Article is considered reasonable for regulatory purposes and is based on historical records, engineering, and scientific methods of study. Larger storms may occur or stormwater runoff amounts and/or stormwater quality may be altered by man-made or natural causes. This Article does not imply that land uses permitted will be free from stormwater damage. This Article shall not create liability on the part of the City Council, Valparaiso City Utilities Board, Plan Commission, City Engineer, or any officer, representative, or employee thereof, for any damage which may result from reliance on this Article or on any administrative decision lawfully made in accordance with this Article.
The words “approve” and “accept”, and their common derivations as used in this Ordinance in relation to plans, reports, calculations, and permits shall mean that City Engineer has reviewed the material produced and submitted by the applicant or his/her agents for general compliance with this Ordinance and the City of Valparaiso Stormwater Technical Standards Manual, and that such compliance would qualify the applicant to receive a stormwater management approval or permit. Such an “approval” or “acceptance” is based on the assumption that the project engineer has followed all appropriate engineering methods in the design. Any stormwater quantity (drainage) or water quality problems associated with the project caused by poor construction by the contractor and/or poor engineering design or judgment, either on-site or off-site, are the responsibility of the developer and the project engineer.
Consideration, design, construction, and maintenance of safety measures for proposed or existing stormwater facilities shall be the responsibility of the developer, applicant, and/or the property owner. City of Valparaiso and its officials and representatives shall not be responsible for maintenance nor liability for any accidents.

Any discharger who accidentally discharges into a waterbody any substance other than stormwater or an exempted discharge shall immediately inform the City Engineer concerning the discharge. A written report concerning the discharge shall be filed with the City of Valparaiso and IDEM, by the dischargers, within five (5) days. The written report shall specify:
A properly reported accidental discharge shall be an affirmative defense to a civil infraction proceeding brought under this Ordinance against a discharger for such discharge. It shall not, however, be a defense to a legal action brought to obtain an injunction, to obtain recovery of costs or to obtain other relief because of or arising out of the discharge. A discharge shall be considered properly reported only if the discharger complies with all the requirements of this Division. This requirement does not relieve discharger from notifying other entities as required by State or Federal regulations.
