Rule le 4306 4306 an and Rule le 4320 4320 Overvie iew

  • These rules apply to any gaseous fuel- or liquid fuel-

fired boiler, steam generator, or process heater with a total rated heat input greater than 5 MMBtu per hour

  • Boilers are external combustion equipment used to

produce hot water or steam

  • Process heaters are combustion equipment that

transfer heat from combustion gases to liquid or gas process streams

  • Steam generators are external combustion equipment

that convert water to steam; most commonly used in thermally enhanced crude oil production

  • These units are used at the following facility types in the Valley:

–Oil and gas production facilities –Petroleum refineries –Food processing operations –Schools, Universities –Correctional facilities –Hospitals –Livestock husbandry operations (dairies, cattle feedlots, etc.) –Electrical utilities –Manufacture and industrial facilities

Current R Rule le 4306 4306 an and Rule le 4320 4320 Requir ireme ments

  • Rule 4306 establishes specific NOx limits for many categories of

boiler/steam generator/process heater units

–NOx limits must be met in order to legally operate in the District –Facilities generally control emissions from these sources through combustion modification or exhaust gas treatment

  • Rule 4320 establishes more strict NOx limits for units in this

source category. Operators are given three options to comply:

–Meet the specified emission limits, or –Pay an emissions fee annually to the District, or –Comply with the low-use provision (fuel limit of ≤ 1.8 billion Btu/yr)

  • Through these rules, NOx emissions from these sources already

reduced by 96%

l Emission R n Reduct eductions N Need eeded

  • Valley’s challenges in meeting federal air quality standards

unmatched due to unique geography, meteorology, and topography

  • Substantial emission reductions needed to achieve PM2.5

standards – need to go beyond already strict limits

  • Commitment in 2018 PM2.5 Plan to evaluate further emissions

reduction opportunities from sources including boilers, steam generators, and process heaters

–Reduce NOx emissions by lowering the NOx emission limits and lowering the more stringent Advanced Emission Reduction Option (AERO) limit for specific classes and categories of units
