Minnesota Rules, Part 7020.2003 - If you are a feedlot owner with less than 300 animal units and have an open lot that does not meet runoff discharge standards for feedlots, you have two options:
Option 1: apply for and obtain an interim permit and fix the problems within 24 months; or
Option 2: sign an agreement at the time of registration (or no later than October 1, 2005) to complete corrective measures under the 2005/2010 Open Lot Agreement. "Open lot certification" provides you additional time to correct problems on an open lot to meet runoff discharge standards. However, your open lot must meet certain eligibility requirements, including registration of the feedlot by January 1, 2002.
If you select the option of open lot certification, you must install interim measures by the year 2005 to reduce manure runoff (as specified in Minnesota Rules, Chapter 7020), and have until the year 2010 to install final measures needed to fully meet the runoff discharge standards for feedlots. If all conditions of the agreement are met, the MPCA will waive civil penalties for past violations of runoff discharge standards and failure to obtain a permit. Your facility is eligible for open lot certification if all the following conditions are satisfied:
Certification forms and additional information are available online or by contacting your RGU. Owners of certified open lots are required to minimize discharges by implementing corrective measures, such as regularly removing manure from open lots. Owners with open lot certification must also complete one of the following interim measures by October 1, 2005:
Concentrated animal feeding operations (CAFOs) and feedlots that are considered imminent health threats are not eligible for the Open Lot Agreement.
In general, feedlot facilities or manure storage areas discharging pollutants to surface waters must comply with water quality limitations given in Minnesota Rules, Part 7050.0215; namely, five day biochemical oxygen demand (BOD5) of the discharge must be less than 25 milligrams per liter (monthly arithmetic mean).
