OAR 340-215-0105
Requirements for Air Contamination Sources
(1)
Calculate and report greenhouse gas emissions using quantification methodologies and report data and information described in 40 C.F.R. part 98 subparts C through UU, as applicable, unless otherwise specified in this rule. Emissions data reports submitted to DEQ must include all emissions with calculation methodology in 40 C.F.R. part 98 subparts C through UU or listed in this division, but may exclude emissions from categorically insignificant activities as defined in OAR 340-200-0020 (General Air Quality Definitions). If categorically insignificant activities cannot be separated from other activities, entities may report aggregate emissions that include categorically insignificant activities;(2)
As applicable, separately report fuel types, quantities, and emissions from fuel combustion reported utilizing 40 C.F.R. part 98, subpart H - Cement Production, subpart W - Petroleum and Natural Gas Systems, and subpart AA - Pulp and Paper Manufacturing quantification methodology;(3)
Provide supplemental documentation, including data inputs for equations to describe how emissions are calculated. Data inputs include but are not limited to fuel throughput, emission factors, and production volumes or product usage used to calculate emissions;(4)
For air contamination sources that include electricity generating units, cogeneration units, or both that meet the applicability requirements of section OAR 340-215-0030 (Applicability)(2), follow the requirements of subparts C and D of 40 C.F.R. part 98, as applicable, in reporting emissions and other data from electricity generating and cogeneration. In addition, such regulated entities must report the following information:(a)
Information for each facility as defined in 40 C.F.R. 98.6, including separately for each facility under the same air contamination source permit: name, address, and contact person and phone number;(b)
If applicable, report facility identification numbers assigned by the U.S. Energy Information Administration, California Air Resources Board and Federal Energy Regulatory Commission’s PURPA Qualifying Facility program;(c)
Report net and gross electricity generated in megawatt-hours; and(d)
Regulated entities that own or operate a cogeneration unit must report the thermal energy in MMBtu generated by a combustion source that is used directly as part of a manufacturing, industrial or commercial process, or as part of as heating or cooling application, separately for the following categories: generated thermal energy provided to end users outside the air contamination source facility boundary and generated thermal energy for on-site industrial applications not related to electricity generation;(5)
An investor-owned utility that owns or operates electric power system facilities as defined in 40 C.F.R. part 98 subpart DD in Oregon must report emissions utilizing calculation methodologies in 40 C.F.R. part 98 subpart DD and must submit an emissions data report including all emissions from electric transmission and distribution equipment and servicing inventory physically located in Oregon for the previous year;(6)
For in-state producers of goods containing fluorinated greenhouse gases in pre-charged equipment or closed-cell foams, report the mass of each fluorinated greenhouse gas in all goods produced in a year and comply with 40 C.F.R. part 98 subpart QQ in reporting emissions to DEQ as modified below:(a)
Report total mass in metric tons of each fluorinated greenhouse gas contained within pre-charged equipment or closed cell foams;(b)
For each type of pre-charged equipment with a unique combination of charge size and charge type, report the identity of the fluorinated greenhouse gas used as a refrigerant or electrical insulator, charge size, holding charge, where applicable and number produced;(c)
For closed–cell foams the identity of the fluorinated greenhouse gas in the foam, the density of the fluorinated GHG in the foam (kilograms of fluorinated greenhouse gas per cubic feet), and the volume of foam produced (cubic feet) for each type of closed–cell foam with a unique combination of F-GHG density and identity; and(d)
Calculate greenhouse gas emissions from foam blowing operations using the following equation. When the blowing agent is a blend of gases, emissions must be calculated separately for each constituent of the blowing agent used during the foam manufacture process.(7)
Calculate and report emissions of CO2 that originate from biomass-derived fuels separately from other greenhouse gas emissions. Use the following procedures when calculating emissions from biomass-derived fuels that are intermixed with fossil fuels:(a)
When calculating emissions from the combustion of municipal solid waste (MSW) or any other fuel for which the biomass fraction is not known, follow the procedures specified in 40 C.F.R. 98.33(e)(3) to specify a biomass fraction;(b)
When calculating emissions from a biomethane and natural gas mixture as described in 40 C.F.R. 98.33(a)(2) calculate emissions based on contractual deliveries of biomethane;(c)
When calculating emissions from a biomethane and natural gas mixture as described in 40 C.F.R. 98.33(a)(4) using a continuous emission monitoring system (CEMS), or when calculating those emissions according to Subpart D of 40 C.F.R. part 98, calculate the biomethane emissions as described above, with the remainder of emission being from natural gas;(d)
When calculating emissions from a biogas and natural gas mixture using 40 C.F.R. 98.33(a)(4) or the carbon content method described in 40 C.F.R. 98.33(a)(3) or when calculating those emissions according to subpart D of 40 C.F.R. part 98, calculate biogas emissions using a carbon content method as described in 40 C.F.R. 98.33(a)(3), with the remainder of emissions being from natural gas.(8)
When reporting emissions from the combustion of natural gas, report the name(s) of the supplier(s) of natural gas to the facility, including information identifying the seller of natural gas, natural gas customer account, and the annual MMBtu delivered to each account according to billing statements (10 therms = 1 MMBtu); and(9)
Report the air permit numbers and NAICS codes according to 40 C.F.R. 98.3(c)(10).
