Section 320

Jan. 25, 2016



Program Authority, Applicability and Purpose. As authorized by RCW 70.94.151, the Board, by this Regulation, classifies air contaminant sources which may cause or contribute to air pollution. This classification is made according to levels and types of emissions and other characteristics that cause or contribute to air pollution. The Board requires both registration and reporting for these classes of air contaminant sources. The classifications are made for the entire area of jurisdiction of the NWCAA and are made with special reference to effects on health, economic and social factors, and physical effects on property. Information collected through the registration program is used to evaluate the effectiveness of air pollution control strategies and to verify source compliance with applicable air pollution requirements.


Registration and Reporting. Any person operating or responsible for the operation of an air contaminant source for which registration and reporting are required, shall register the source with the NWCAA. The owner or operator shall make reports to the NWCAA containing information as may be required by the NWCAA concerning location, size, and height of contaminant outlets, processes employed, nature of the air contaminant emission, and such other information as is relevant to air pollution and available or reasonably capable of being assembled.


Annual Registration Fees. An annual registration fee shall be paid by all registered sources. The Board has determined the fee for each class of air contaminant source to be as shown in Section 324.1. The amount of fees collected shall not exceed the costs of administering this registration program, which shall be defined as:

a) initial registration and annual or other periodic reports from the source owner or operator providing the information directly related to air pollution registration;

b) on-site inspections necessary to verify compliance with registration requirements;

c) data storage and retrieval systems necessary for support of the registration program;

d) emission inventory reports and emission reduction credits computed from information provided by sources pursuant to the requirements of the registration program;

e) staff review, including engineering analysis for accuracy and completeness, of information provided by sources pursuant to the requirements of the registration program;

f) clerical and other office support provided in direct furtherance of the registration program; and

g) administrative support provided in directly carrying out the registration program.



Any registered source which does not pay the annual registration fee by the end of the registration period shall be considered a new source and shall submit a “Notice of Construction and Application for Approval” and receive approval from the Board prior to resumption of operation or re-entry into the jurisdiction of the NWCAA.
