Sec2 450 - EMISSION STANDARDS - FOREWORD

Universal Citation: WA Admin Code 450

Current through Register Vol. 24-18, September 15, 2024

450.1 The NWCAA recognizes the need for accurate source air contaminant data when attempting to correlate ground level concentrations with source emissions or when calculating the expected ground level concentrations.

450.2 Since accurate determination of the required data is a complex process, procedures for obtaining such data should be developed from the emission regulation set forth herein.

450.3 In exercising judgement regarding possible ground level concentrations from stack emission data, three desirable elements are:

450.31 Source emission rate data obtained by actual measurement.

450.32 A mathematical model of the community diffusion situation.

450.33 Values for parameters of the model.

450.4 The NWCAA may develop emission standards for pollutants presently not being emitted in the area of jurisdiction to serve as guides for industries considering locating here. These are to be based on the best control experience elsewhere in the nation and consistent with latest technological achievements.
