Chapter 6 - Construction Site Stormwater Run-Off Control MCM 

6.0        Introduction 

This chapter describes the construction site stormwater run-off control minimum control measure, the fourth of six measures the Operator of a Phase II regulated small Municipal Separate Storm Sewer System (MS4) is required to include in its stormwater management program to meet the conditions of its National Pollutant Discharge Elimination System (NPDES) permit.  The construction site stormwater runoff control MCM regulates areas undergoing new development or redevelopment of one acre or more. 

Construction site stormwater management in areas undergoing new development or redevelopment is necessary because polluted stormwater run-off from construction sites often flows to MS4 conveyances and ultimately discharges into receiving waters untreated.  

Each section of this plan describes a Best Management Practice (BMP).  Each BMP is accompanied by its own implementation schedule. The implementation schedule informs the MS4 Operator and their designated personnel of the tasks to complete for each year. The MS4 Operator will require that the parties responsible for each construction site stormwater run-off control record and report annually on the items to be tracked so that the MS4 Operator may include them in the annual report to IDEM.

Measurable Goal: The construction site run-off control program aims to reduce the amount of total suspended solids leaving individual construction sites by 80%. The goal is to achieve the 80% reduction during the construction period of any new development required to gain local approval. 

The following is the construction site stormwater run-off control program. 

6.1    Development of a Regulatory Mechanism 

The purpose of the regulatory mechanism for construction site stormwater run-off control is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within the MS4 area during construction activities.  This regulatory mechanism applies to the following sites with land-disturbing activities: those involving construction activities with a land disturbance greater than or equal to one acres, or disturbances of less than one acre of land that are part of a larger common plan of development or sale if the larger common plan will ultimately disturb one or more acres of land. 

The City of Logansport will use an overall Stormwater Ordinance with a Chapter titled Erosion and Sediment Control for its regulatory mechanism.  The Ordinance will be written to be in accordance with 327 IAC 15-13 and 327 IAC 15-5. 

The Ordinance will include construction site plan submittal requirements, a general description of the Cityís review and inspection process, and a description of enforcement procedures.

6.1.1    Implementation Schedule 

The implementation of the Cityís construction site run-off control regulatory mechanism, otherwise referred to as the Erosion and Sediment Control Chapter of the Stormwater Ordinance, will be the responsibility of the MS4 Operator who will pursue the following schedule:  

Year 1 (ending Nov 2004):  Develop a draft Chapter for construction stormwater run-off.  The City will submit the draft Chapter to DNR for their review and comments. 

Year 2 (ending Nov 2005):  Update the Erosion and Sediment Control Chapter as necessary. The City will then adopt the Chapter as part of the Stormwater Ordinance. 

Year 3 (ending Nov 2006):  Review the Erosion and Sediment Control Chapter  and note any suggested improvements.  Update the Chapter and amend the Stormwater Ordinance as necessary. 

Year 4 (ending Nov 2007):  Review the Erosion and Sediment Control Chapter  and note any suggested improvements.  Update the Chapter and amend the Stormwater Ordinance as necessary. 

Year 5 (ending Nov 2008):   Review the Erosion and Sediment Control Chapter  and note any suggested improvements.  Update the Chapter and amend the Stormwater Ordinance as necessary. 

6.1.2    Items to be Tracked 

The following items will be recorded on the corresponding reporting form located at the end of this chapter.

  •  Number and type of suggested improvements for the Erosion and Sediment Control Chapter ; and

  • Number and description of changes made to the Erosion and Sediment Control Chapter.

6.2    Site Plan Review Process 

The development standards will be written to be in accordance with 327 IAC 15-13 and 327 IAC 15-5.  According to 327 IAC 15-13, the permitting process and associated timetables for site plan and application submittals listed in 327 IAC 15-5 do not have to be followed.  The City of Logansport will develop standardized timetables for all construction site plan reviews and application submittals. 

The City of Logansport, through the Stormwater Management Board, reviews construction site plans submitted for non-MS4 operated projects to the City, and inspects the sites during construction.  The City will give the SWCD the opportunity to review each of these plans prior to the Cityís approval of the submitted plans.  Failure of the SWCD to respond within a predetermined time period should not delay final action of the MS4 Operator to approve plans. 

After the City gives approval, the construction site operator is responsible to submit a Notice of Intent (NOI) Letter to IDEM. 

Before construction begins, the City will perform a site inspection to verify that BMPs that were proposed in the permit application have been installed.  Periodic site inspections will be performed for the duration of the construction period.  Inspection of construction sites will be prioritized based on size of development, proximity of the development to sensitive areas, and sites with a history of noncompliance. 

For sites found to be in noncompliance with their approved permit, enforcement actions will be taken, such as, stop work orders and administrative fines. 

For the duration of the MS4 permit term, the SWCD will be given the opportunity to review and inspect all MS4 operated projects.  Only after the local SWCD Director gives written permission to the City giving them the authority to perform self monitoring will the MS4 Operator will no longer be required to submit MS4 operated projects to the SWCD for their review. 

For MS4 operated projects, the site plan submittal may include additional items that are not required for non-MS4 operated projects. The additional items include a traffic phasing plan for those projects that have the potential to alter vehicular traffic routes, utility relocation areas, material hauling and transportation routes/roads, borrow pits, temporary staging and materials stock-pile areas, and temporary disposal areas for waste materials. These additional items will only be for those projects that have the potential to directly impact the water quality of the MS4ís receiving streams. This could be caused by construction activity such as temporary bridges for bridge replacement projects or where road construction activity is adjacent to a river or stream bank. It also includes areas where temporary roads must be constructed. Projects that use existing roads for rerouting need not require traffic phasing plans. 

The City will review all projects in coordination with the Logansport/Cass County Plan Commission within the MS4 area.  They may choose to review projects within the extra-jurisdictional area and provide comments to the extra-jurisdictional review authorities for their consideration. 

The site plan review process is generally described in the Ordinance and more detail will be provided in the City of Logansportís Development Standards. 

The MS4 Operator will be required to submit a monthly summary report of construction projects to IDEM.  This certification form is located in Appendix F, State Form 51276 (R3/ 11-03). 

6.2.1    Implementation Schedule 

The implementation of the development of Site Plan Review Procedures will be the responsibility of the MS4 Operator who will pursue the following schedule:  

Year 1 (ending Nov 2004):  Approve the establishment of a local plan review and comment procedures for all construction site plans and construction site inspections, as described above and in the City of Logansportís Development  Manual. 

Year 2 (ending Nov 2005):  Review plan review and comment procedures for all construction site plans and construction site inspections and update as necessary.   

Year 3 (ending Nov 2006):  Review plan review and comment procedures for  all construction site plans and construction site inspections and update as necessary.   

Year 4 (ending Nov 2007):  Review plan review and comment procedures for  all construction site plans and construction site inspections and update as necessary.   

Year 5 (ending Nov 2008):   Review plan review and comment procedures for  all construction site plans and construction site inspections and update as necessary.   

6.2.2    Items to be Tracked 

The following items will be recorded on the corresponding reporting form located at the end of this chapter. 

  •  Number of reviews by the SWCD; 
     

  •  Number of construction sites permitted for stormwater quality;

  •  Number of construction sites inspected; and

  •  Number and type of enforcement actions taken against construction site operators.

6.3    Public Participation 

The MS4 Operator will establish procedures for receipt and consideration of public inquiries, concerns, and requests for information regarding local construction activities.  These procedures will, at a minimum, implement a tracking process in which submitted public information, both written and verbal, documenting it and giving it to the appropriate staff. 

These procedures, as well as their implementation timeline and measurable goal are addressed in Chapter 4, Public Participation and Involvement. 

6.4    Annual Training of MS4 Personnel 

Current Employees: Current employees whose work could affect stormwater quality, including but not limited to personnel involved in site plan review, inspection and enforcement, will be required to complete training on stormwater related policies, programs, and procedures.  This training will be documented.  The documentation will be retained by the City. 

During subsequent years, employees will be required to complete an annual refresher training program.  This training will be documented.  The documentation will be retained by the City. 

New Employees:  New employees whose work involves construction stormwater run-off control will be required to complete training.  This training will take place within the first two months of employment.  This training will involve instruction on plan review, inspection protocol, enforcement procedures and appropriate control measures.  This training will be documented.  The documentation will be retained by the City. 

6.4.1    Implementation Schedule 

The implementation of training for MS4 personnel will be the responsibility of the MS4 Operator who will pursue the following schedule: 

Year 1 (ending Nov 2004):  Approve the development of annual training for MS4 personnel on construction stormwater run-off controls, as described above.
