limitation is assumed. Compliance with the production restriction is based upon the recordkeeping in d)(3). [Authority for term: PTI 02-21983 and OAC rule 3745-77-07(C)(1)] Emission Limitation: Visible PE from any stack serving this emissions unit shall not exceed 5% opacity, as a 6-minute average. Applicable Compliance Method: If required, compliance with the above visible emission limitation shall be determined using Method 9 of 40 CFR Part 60, Appendix A. [Authority for term: PTI 02-21983, OAC rule 3745-15-04(A) and OAC rule Emission Limitation: Visible emissions of fugitive dust from this emissions unit shall not exceed 5% opacity, as a 3-minute average. Applicable Compliance Method: If required, compliance with the above visible emission limitation shall be determined using Method 9 of 40 CFR Part 60, Appendix A, except that the data reduction and average opacity calculation shall be based upon sets of twelve consecutive visible particulate emission observations recorded at fifteen-second intervals. [Authority for term: PTI 02-21983, OAC rule 3745-15-04(A) and OAC rule Miscellaneous Requirements Modeling to demonstrate compliance with the Ohio EPA's "Air Toxic Policy" was not necessary because the increase in emissions due to the modification(s) to the emissions unit was less than 1 tpy of each toxic pollutant that has a listed Threshold Limit Value (TLV), as documented in the most current version of the American Conference of Governmental Industrial Hygienists' (ACGIH's) handbook entitled "TLVs and BEIs" ("Threshold Limit Values for Chemical Substances and Physical Agents, Biological Exposure Indices").

= emission factor of 2.24 lbs of PM10/ton from FIRE ver 6.25 SCC 3-04-003-31; P = maximum annual process weight rate (19,000 tpy); and CE = fractional capture efficiency of baghouse = 0.99. [Authority for term: PTI 02-20457 and OAC rule 3745-77-07(C)(1)] Emission Limitation: OC emissions shall not exceed 12.00 lbs/hr. Applicable Compliance Method: Compliance with the hourly emission limitation shall be determined using an emission factor of 1.20 lbs/ton from FIRE version 6.25 SCC 3-04-003-31 and the maximum hourly production rate of 10 TPH. [Authority for term: PTI 02-20457 and OAC rule 3745-77-07(C)(1)] Emission Limitation: CO emissions shall not exceed 10.00 lbs/hr. Applicable Compliance Method: Compliance with the hourly emission limitation shall be determined using an emission factor of 1.00 lb/ton from Waupaca foundry RBLC determination in Indiana and the maximum hourly production rate of 10 TPH. [Authority for term: PTI 02-20457 and OAC rule 3745-77-07(C)(1)] Emission Limitation: Emissions of PM/PM10 from the baghouse stack serving this emissions unit and emissions units F021, P021 and P902 shall not exceed 26.28 tpy based upon a rolling, 12-month period. Applicable Compliance Method: The annual emission limitation was established using the allowable grain loading limit for the baghouse stack (0.010 gr/dscf), the baghouse flow rate 70,000 scfm and potential operating hours of 8,760 hrs/yr. Therefore, compliance with the annual limit is assumed, as long as compliance with the grain loading limit is maintained. [Authority for term: PTI 02-20457 and OAC rule 3745-77-07(C)(1)] Emission Limitation: Fugitive PM10 emissions shall not exceed 0.21 tpy based upon a rolling, period. OC emissions shall not exceed 11.40 tpy based upon a rolling, 12-month period.
Additional Terms and Conditions The permittee shall employ best available control measures consisting of normal operation and maintenance to ensure compliance with the opacity limitation specified above. If at any time compliance with the opacity limitation is not maintained, the permittee shall employ additional control measures. The hourly emission limitations specified above represent the potential to emit for this emissions unit. Therefore, no recordkeeping or reporting requirements are specified to demonstrate ongoing compliance with these limits. This emissions unit is exempt from the requirements of this rule as long as no photochemically reactive materials are employed. Note: The requirements established under OAC rule 3745-21-07 shall cease to be effective and federally enforceable on the date the U.S. EPA approves the current rule as a revision to the Ohio SIP for the control of organic compounds. Operational Restrictions Annual material throughput for this emissions unit, in terms of core wash and core wash thinner employed, shall not exceed 4,550 gallons per year and 3,550 gallons per year, respectively. This material throughput restriction shall be based on a rolling, 12-month summation of the monthly production rates. [Authority for term: PTI 02-21651 and OAC rule 3745-77-07(A)(1)] The permittee shall employ core wash with no greater than 5.80 lbs of VOC/gallon and no more than 4.20 lbs of solids/gallon. [Authority for term: PTI 02-21651 and OAC rule 3745-77-07(A)(1)] The permittee shall employ core wash thinner with no greater than 6.68 lbs of VOC/gallon. [Authority for term: PTI 02-21651 and OAC rule 3745-77-07(A)(1)] The permittee shall employ no photochemically reactive materials in this emissions unit, as photochemically reactive material is defined in OAC rule 3745-21-01(C)(5). [Authority for term: PTI 02-21651 and OAC rule 3745-77-07(A)(1)] Monitoring and/or Recordkeeping Requirements The permittee shall maintain the following monthly records for this emissions unit: the name and identification number of each material employed; an indication of whether or not each material is a photochemically reactive material as defined in OAC rule 3745-21-01(C)(5);
