(A) An approved stormwater management permit shall be obtained prior to the initiation of any construction activities. In order to obtain a stormwater management permit, the applicant shall be the entity responsible for accomplishing the construction activity for which the stormwater management permit was issued. In granting a stormwater management permit, the city may impose such terms and conditions as are reasonably necessary to meet the purpose of this chapter. The entity shall ensure compliance with such terms and conditions. Noncompliance with the terms and conditions of permits will be subject to enforcement as described in § 54.21.
(B) The entity shall inform all general contractors, construction management firms, grading or excavating contractors, utility contractors and the contractors that have primary oversight on individual building lots of the terms and conditions of the stormwater management permit and the schedule for proposed implementation.
(1) The project site owner must submit an application for a stormwater management permit to the city and IDEM, including an initial notice of intent (NOI), construction plan sheets, stormwater drainage technical report, a stormwater pollution prevention plan (SWPPP) for active construction sites, a post-construction SWPPP and the applicable permit fees to the city (city’s inspection fees ordinance). All plans, reports, calculations, and narratives shall be prepared in accordance with the city’s Utility and Infrastructure Construction Standards and Specifications Manual and signed and sealed by a professional engineer, registered by the state.
(2) (a) The city will review each application for a stormwater management permit to determine its conformance with the provisions of this chapter. The city will take one of the following actions:
1. Approve the SWPPP for active construction sites and for post-construction and provide a technical review and comment form stating the “plan is adequate”;
2. Approve the SWPPP for active construction sites and for post-construction subject to such reasonable conditions as may be necessary to secure substantially the objectives of this chapter, and issue the technical review and comment form stating the “plan is adequate” with said conditions outlined; and
3. Provide a technical review and comment form stating the “plan is deficient” and indicating the reason(s) and procedure for submitting a revised application and/or submission.
(b) Any changes or deviations in the detailed plans and specifications after approval of the applicable stormwater management permit shall be filed with, and accepted by, the city prior to the commencement of construction activity involving the change. Applicable plan review fees are due in accordance with the city’s inspection fee ordinance before any plan will be approved.
(3) (a) After receiving a technical review and comment form stating the “plan is adequate”, the project site owner must notify the city and IDEM 48 hours before beginning construction. Notification shall be in the form of an updated NOI form along with proof of publication of public notice. The applicant is also responsible for any IDEM-required NOI fee. The publication must include the following:
“(Company name, address) is submitting an NOI letter to notify the City of Westfield and the Indiana Department of Environmental Management of our intent to comply with the requirements of the City of Westfield Stormwater Management Ordinance, as well as the requirements of 327 I.A.C. 15-5 and 327 I.A.C. 15-13, to discharge stormwater from construction activities for the following project: (name of the construction project, address of the location of the construction project, and Parcel Identification Number). Run-off from the project site will discharge to (stream(s) receiving the discharge(s)).”
(b) Once a permit has been issued and the updated NOI submitted to the city and IDEM 48 hours before beginning construction, construction may commence. A stop work order per § 54.22 shall be issued by the city for all projects that are proceeding without such notification.
(4) Once construction starts, the project owner shall monitor construction activities and inspect all stormwater pollution prevention measures in compliance with the city’s applicable ordinances and the terms and conditions of the approved permit. Lack of maintenance of stormwater pollution prevention measures during construction or failure to implement the approved SWPPP by the approved schedule of implementation shall constitute a violation of this chapter, subject to enforcement under the provisions of this chapter.
(5) Upon completion of construction activities, as-built plans must be submitted to the city.
(6) The entity must submit a notice of termination (NOT) letter to the city once the construction site has been stabilized and all temporary erosion and sediment control measures have been removed. The city shall inspect the construction site and verify the requirements for an NOT have been met. Once the applicant receives a “verified” copy of the NOT, they must forward a copy to IDEM.
