AMENDATORY SECTION(Amending Order 93-03, filed 8/20/93, effective 9/20/93)

WAC 173-400-040
General standards for maximum emissions.

All sources and emissions units are required to meet the emission standards of this chapter.      Where an emission standard listed in another chapter is applicable to a specific emissions unit, such standard will take precedent over a general emission standard listed in this chapter.      When two or more emissions units are connected to a common stack and the operator elects not to provide the means or facilities to sample emissions from the individual emissions units, and the relative contributions of the individual emissions units to the common discharge are not readily distinguishable, then the emissions of the common stack must meet the most restrictive standard of any of the connected emissions units.      Further, all emissions units are required to use reasonably available control technology (RACT) which may be determined for some sources or source categories to be more stringent than the applicable emission limitations of any chapter of Title 173 WAC.      Where current controls are determined to be less than RACT, ecology or the authority shall, as provided in ((section 8, chapter 252, Laws of 1993)) RCW 70.194.154, define RACT for each source or source category and issue a rule or regulatory order requiring the installation of RACT.

     (1) Visible emissions.      No person shall cause or permit the emission for more than three minutes, in any one hour, of an air contaminant from any emissions unit which at the emission point, or within a reasonable distance of the emission point, exceeds twenty percent opacity except:

     (a) When the emissions occur due to soot blowing/grate cleaning and the operator can demonstrate that the emissions will not exceed twenty percent opacity for more than fifteen minutes in any eight consecutive hours.      The intent of this provision is to permit the soot blowing and grate cleaning necessary to the operation of boiler facilities.      This practice, except for testing and trouble shooting, is to be scheduled for the same approximate times each day and ecology or the authority be advised of the schedule.

     (b) When the owner or operator of a source supplies valid data to show that the presence of uncombined water is the only reason for the opacity to exceed twenty percent.

     (c) When two or more sources are connected to a common stack, ecology or the authority may allow or require the use of an alternate time period if it is more representative of normal operations.

     (d) When an alternate opacity limit has been established per RCW 70.94.331 (2)(c).

     (2) Fallout.      No person shall cause or permit the emission of particulate matter from any source to be deposited beyond the property under direct control of the owner(s) or operator(s) of the source in sufficient quantity to interfere unreasonably with the use and enjoyment of the property upon which the material is deposited.

     (3) Fugitive emissions.      The owner or operator of any emissions unit engaging in materials handling, construction, demolition or any other operation which is a source of fugitive emission:

     (a) If located in an attainment area and not impacting any nonattainment area, shall take reasonable precautions to prevent the release of air contaminants from the operation.

     (b) If the emissions unit has been identified as a significant contributor to the nonattainment status of a designated nonattainment area, shall be required to use reasonable and available control methods, which shall include any necessary changes in technology, process, or other control strategies to control emissions of the contaminants for which nonattainment has been designated.

     (4) Odors.      Any person who shall cause or allow the generation of any odor from any source which may unreasonably interfere with any other property owner's use and enjoyment of his property must use recognized good practice and procedures to reduce these odors to a reasonable minimum.

     (5) Emissions detrimental to persons or property.      No person shall cause or permit the emission of any air contaminant from any source if it is detrimental to the health, safety, or welfare of any person, or causes damage to property or business.

     (6) Sulfur dioxide.

     No person shall cause or permit the emission of a gas containing sulfur dioxide from any emissions unit in excess of one thousand ppm of sulfur dioxide on a dry basis, corrected to seven percent oxygen for combustion sources, and based on the average of any period of sixty consecutive minutes, except:

     When the owner or operator of an emissions unit supplies emission data and can demonstrate to ecology or the authority that there is no feasible method of reducing the concentration to less than one thousand ppm (on a dry basis, corrected to seven percent oxygen for combustion sources) and that the state and federal ambient air quality standards for sulfur dioxide will not be exceeded.      In such cases, ecology or the authority may require specific ambient air monitoring stations be established, operated, and maintained by the owner or operator at mutually approved locations.      All sampling results will be made available upon request and a monthly summary will be submitted to ecology or the authority.

     (7) Concealment and masking.      No person shall cause or permit the installation or use of any means which conceals or masks an emission of an air contaminant which would otherwise violate any provisions of this chapter.

     (8) Fugitive dust sources.

     (a) The owner or operator of a source of fugitive dust shall take reasonable precautions to prevent fugitive dust from becoming airborne and shall maintain and operate the source to minimize emissions.

     (b) The owner(s) or operator(s) of any existing source(s) of fugitive dust that has been identified as a significant contributor to a PM-10 nonattainment area shall be required to use reasonably available control technology to control emissions.      Significance will be determined by the criteria found in WAC 173-400-113(3).

     (a) All existing catalytic cracking units shall meet all provisions of WAC 173-400-040 (2), (3), (4), (5), (6), and (7) and:

     (i) No person shall cause or permit the emission for more than three minutes, in any one hour, of an air contaminant from any catalytic cracking unit which at the emission point, or within a reasonable distance of the emission point, exceeds forty percent opacity.

     (ii) No person shall cause or permit the emission of particulate material in excess of 0.46 grams per dry cubic meter at standard conditions (0.20 grains/dscf) of exhaust gas.

     (b) All new catalytic cracking units shall meet all provisions of WAC 173-400-115.

     (6) Other wood waste burners.

     (a) Wood waste burners not specifically provided for in this section shall meet all provisions of WAC 173-400-040.

     (b) Such wood waste burners shall utilize RACT and shall be operated and maintained to minimize emissions.

     (7) Sulfuric acid plants.

     No person shall cause to be discharged into the atmosphere from a sulfuric acid plant, any gases which contain acid mist, expressed as H2SO4, in excess of 0.15 pounds per ton of acid produced.      Sulfuric acid production shall be expressed as one hundred percent H2SO4.

     (8) Sewage sludge incinerators.      Standards for the incineration of sewage sludge found in 40 CFR Part 503 subparts A (General Provisions) and E (Incineration) in effect on July 1, 1997, are adopted by reference.

     (9) Municipal solid waste landfills constructed, reconstructed, or modified before May 30, 1991. A municipal solid waste landfill (MSW landfill) is an entire disposal facility in a contiguous geographical space where household waste is placed in or on the land. A MSW landfill may also receive other types of waste regulated under Subtitle D of the Federal Recourse Conservation and Recovery Act including the following: Commercial solid waste, nonhazardous sludge, conditionally exempt small quantity generator waste, and industrial solid waste. Portions of an MSW landfill may be separated by access roads. A MSW landfill may be either publicly or privately owned. A MSW landfill may be a new MSW landfill, an existing MSW landfill, or a lateral expansion.

     (a) Applicability. These rules apply to each existing MSW landfill constructed, reconstructed, or modified before May 30, 1991. (See WAC 173-400-115(2) for MSW landfills constructed, reconstructed, or modified on or after May 30, 1991.)

     (b) Exceptions. Any physical or operational change to an existing MSW landfill made solely to comply with these rules is not considered a modification or rebuilding.

     (c) Recordkeeping and reporting. All existing MSW landfills must follow the recordkeeping and reporting requirements in 40 CFR 60.757 (submittal of an initial design capacity report) and 40 CFR 60.758 (recordkeeping requirements). Exceptions to these requirements are located in 40 CFR 60.24.

     (d) Test methods and procedures.

     (i) All existing MSW landfills must calculate the landfill nonmethane organic compound (NMOC) emission rates following the procedures listed in 40 CFR 60.754.

     (ii) Gas collection and control systems must meet the requirements in 40 CFR 60.752 (b)(2)(ii) through the following procedures:

     (A) The systems must follow the operational standards in 40 CFR 60.753.

     (B) The systems must follow the compliance provisions in 40 CFR 60.755 (a)(1) through (a)(6) to determine whether the system is in compliance with 40 CFR 60.752 (b)(2)(ii).

     (C) The system must follow the applicable monitoring provisions in 40 CFR 60.756.

     (e) Conditions. Existing MSW landfills that meet the following conditions must install a gas collection and control system:

     (i) The landfill accepted waste at any time since November 8, 1987, or the landfill has additional design capacity available for future waste deposition;

     (ii) The landfill has design capacity greater than or equal to 2.5 million megagrams or 2.5 million cubic meters. The landfill may calculate design capacity in either megagrams or cubic meters for comparison with the exception values. Any density conversions shall be documented and submitted with the report; and

     (iii) The landfill has a nonmethane organic compound (NMOC) emission rate of 50 megagrams per year or greater.

     (f) Change in conditions. After the adoption date of this rule, a landfill that meets all three conditions in (e) of this subsection must comply with all the requirements of this section within thirty months of the date when the conditions were met. This change will usually occur because the NMOC emission rate equaled or exceeded the rate of 50 megagrams per year.

     (g) Gas collection and control systems.

     (i) Gas collection and control systems must meet the requirements in 40 CFR 60.752 (b)(2)(ii).

     (ii) The design plans must be prepared by a licensed professional engineer and submitted to ecology within one year after the adoption date of this section.

     (iii) The system must be installed within eighteen months after the submittal of the design plans.

     (iv) The system must be operational within thirty months after the adoption date of this section.

     (v) The emissions that are collected must be controlled in one of three ways:

     (A) An open flare designed and operated according to 40 CFR 60.18;

     (B) A control system designed and operated to reduce NMOC by 98 percent by weight; or

     (C) An enclosed combustor designed and operated to reduce the outlet NMOC concentration to 20 parts per million as hexane by volume, dry basis to three percent oxygen, or less.

WAC 173-400-104
Registration fees.

(1) Registration fee determination.      In counties without an active local air pollution control authority, ecology shall establish registration fees based on workload using the process outlined below.      The fees collected shall be sufficient to cover the direct and indirect costs of administering the registration program within ecology's jurisdiction.

     (2) Budget preparation.      Ecology shall conduct a workload analysis projecting resource requirements for administering the registration program.      Workload estimates shall be prepared on a biennial basis and shall estimate the resources required to perform registration program activities listed in WAC ((173-400-097)) 173-400-099(2).      Ecology shall prepare a budget for administering the registration program using workload estimates identified in the workload analysis for the biennium.

     (3) Registration fee schedule.      Ecology's registration program budget shall be distributed to sources located in its jurisdiction according to the following:

     (a) Sources requiring periodic registration and inspections shall pay an annual registration fee of four hundred dollars.

     (b) Sources requiring annual registration and inspections shall pay a registration fee comprised of the following three components:

     (i) Flat component.      This portion of a source's fee shall be calculated by the equal division of thirty-five percent of the budget amount allocated to annual registration sources by the total number of sources requiring annual registration.

     (ii) Complexity component.      Each source is assigned a complexity rating of 1, 3, or 5 which is based on the estimated amount of time needed to review and inspect the source.      This portion of the fee is calculated by dividing forty percent of the budget amount allocated to annually registered sources by the total complexity of sources located in ecology's jurisdiction.      The quotient is then multiplied by an individual source's complexity rating to determine that source's complexity portion of the fee.

     (iii) Emissions component.      This portion of a source's fee is calculated by dividing twenty-five percent of the budget amount allocated to annually registered sources by the total billable emissions from those sources.      The quotient is then multiplied by an individual source's billable emissions to determine that source's emissions portion of the fee.      Billable emissions include all air pollutants except carbon monoxide and total suspended particulate.

     (4) Regulatory orders.      Owners or operators registering a source as a synthetic minor must obtain a regulatory order which limits the source's emissions.      The owner will be required to pay a fee based on the amount of time required to research and write the order multiplied by an hourly rate of sixty dollars.

     (5) Fee reductions for pollution prevention initiatives.      Ecology may reduce registration fees for an individual source if that source demonstrates the use of approved pollution prevention measures or best management practices beyond those required of the source.

     (6) Fee reductions for economic hardships.      If a small business owner believes the registration fee results in an extreme economic hardship, the small business owner may request an extreme hardship fee reduction.      The owner or operator must provide sufficient evidence to support a claim of an extreme hardship.      The factors which ecology may consider in determining whether an owner or operator has special economic circumstances and in setting the extreme hardship fee include: Annual sales; labor force size; market conditions which affect the owner's or operator's ability to pass the cost of the registration fee through to customers; average annual profits, and cumulative effects of multiple site ownership.      In no case will a registration fee be reduced below two hundred dollars.

     (7) Fee payments.      Fees specified in this section shall be paid within thirty days of receipt of ecology's billing statement.      All fees collected under this regulation shall be made payable to the Washington department of ecology.      A late fee surcharge of fifty dollars or ten percent of the fee, whichever is more, may be assessed for any fee not received after the thirty-day period.

     (8) Dedicated account.      All registration fees collected by ecology shall be deposited in the air pollution control account.

     (9) Tracking revenues, time, and expenditures.      Ecology shall track revenues collected under this subsection on a source-specific basis.      Ecology shall track time and expenditures on the basis of ecology budget functions.
