	~~Facility Runoff Control Plans (FRCP) are required at all MoDOT maintenance and operations areas referenced above.~~

			[[media:127.29.9 FRCP.pdf\|Facility Runoff Control Plans (FRCP)]] are required at all MoDOT maintenance and operations areas referenced above. These plans outline good housekeeping and pollution prevention best management practices to reduce or eliminate pollutant laden runoff from MoDOT’s maintenance and operations facilities. The plans outline target pollutant education, inspection obligations, and corrective action guidance for those facilities and operations within the TS4 area.

			FRCP inspections are required to be completed once every six (6) months. Inspections must be completed by a qualified facility inspector. Qualifications are outlined in the FRCP plan. Inspection forms and corrective measure documentation forms are included in the FRCP plan and are to be maintained for a period of three (3) years at the facility or electronically as determined by district maintenance management. FRCP plans, inspections, and corrective actions identified during inspections must be accessible and made available to regulating agency personnel upon request.

			==127.29.9 Public Involvement for Stormwater==

			A public hearing may be requested during the public notice period for MoDOT’s TS4 Site-specific State Operating Permit. The public notice will be posted on [http://www.modot.org/stormwater/ MoDOT’s stormwater page] and emailed to media statewide when MoDOT is submitting a renewal application to the MDNR, typically every five years.

			The request must give reasonable cause for holding the hearing. A public hearing will be held if there is significant technical merit and concern related to the responsibilities of MoDOT. At least 30 days prior to the hearing MoDOT will post public notice of the hearing. The hearing will be held in the geographic area appropriate to the request.

	In project areas where a TMDL is in effect, it is feasible to tailor a permanent BMP to the pollutant identified. The American Association of State Highway Transportation Organization’s (AASHTO) ''Drainage Manual 2014'' provides a table (Table 7-2) with the “Effectiveness and Applicability of Management Measures” for various permanent BMP control measures’ ability to remove specific pollutant types such as particulates, heavy metals, pesticides and organics. An example in table shows that curb elimination (promoting sheet flows) is highly effective at removing particulates, heavy metals and organics.

			'''Special Watersheds where MoDOT has been assigned a Wasteload Allocation (WLA)'''

			There are currently 4 watersheds where MoDOT has been assigned a WLA. These are all in the St. Louis District. They are Coldwater Creek, Watkins Creek, Creve Coeur Creek and Fishpot Creek. When a new or redevelopment project is within any of these watersheds, MoDOT will first consider and give more value to media filters, bioretention and retention as BMPs. This shall be done in accordance with the MCM5 requirement to consider BMPs when a project disturbs ≥ 1 acre, is within the TS4 area, and meets the definition of redevelopment or new development.

	By the final RES stage submittal, the project shall include the location of the permanent BMP(s) on the plan sheets and noted under Water Quality/Stormwater section, for entry into the BMP database.
