What to do / Why to do it
Operation and Maintenance of Wall/Panel Filter: The Permittee shall operate and maintain the wall/panel filter according to the control equipment manufacturer’s specifications, shall conduct inspections, and maintain documentation of those actions as required by Minn. R. 7011.0075, subp. 2(A) to 2(I). The Permittee shall keep copies of the O & M Plan available onsite for use by staff and MPCA staff. / 40 CFR Section 64.8; Minn. R. 7017.0200; Minn. R. 7011.0080; Minn. R. 7007.0800, subp. 4
PM control efficiency: The Permittee shall operate and maintain the control equipment such that it achieves an overall control efficiency of particulate matter: greater than or equal to <85/68> percent efficiency. / Minn. R. 7011.0080; Minn. R. 7007.0800, subp. 4
PM10 control efficiency: The Permittee shall operate and maintain the control equipment such that it achieves an overall control efficiency of particulate matter with an aerodynamic diameter less than 10 microns: greater than or equal to <85/68> percent efficiency. / Minn. R. 7011.0080; Minn. R. 7007.0800, subp. 4
PM2.5 control efficiency: The Permittee shall operate and maintain the control equipment such that it achieves an overall control efficiency of particulate matter with an aerodynamic diameter less than 2.5 microns: greater than or equal to <65/52> percent efficiency. / Minn. R. 7007.0800, subp. 2
Daily Inspections: Once each operating day, if the spray booth in operation, the Permittee shall visually inspect the condition of each wall/panel filter with respect to alignment, saturation, tears, holes and any other matter than may affect the filter's performance. The Permittee shall maintain a daily written record of filter inspections. / Minn. R. 7011.0080;
Minn. R. 7007.0800, subp. 4
Periodic Inspections: At least once per calendar quarter, or more frequently as required by the manufacturing specifications, the Permittee shall inspect the control equipment components. The Permittee shall maintain a written record of these inspections. / Minn. R. 7011.0080;
Minn. R. 7007.0800, subp. 4
Recordkeeping of Corrective Actions: If the filters or any of their components are found during the inspections to need repair, the Permittee shall follow the O & M Plan for the wall/panel filter and take corrective action as soon as possible.
