PART 57--PRIMARY NONFERROUS SMELTER ORDERS--Table of Contents
 
           Subpart E--Fugitive Emission Evaluation and Control
 
Sec. 57.502  Evaluation.

    (a) Evaluation at the time of application. Any smelter owner may 
demonstrate at the time of application for an NSO that the smelter's 
SO2 fugitive emissions will not cause or significant 
contribute to violations of the NAAQS in the smelter's DLA. If such 
demonstration is not made, the smelter owner shall submit the design and 
workplan for a study adequate to assess the sources of significant 
fugitive emissions from the smelter and their effects upon ambient air 
quality.
    (b) Evaluation during the first 6 months of the NSO. The design and 
workplan of the study shall be approved, if adequate, by the issuing 
agency and included in the NSO. The study shall commence no later than 
the date when the NSO becomes effective and an analysis of its results 
shall be submitted to the issuing agency within 6 months of the 
effective date of the NSO. The study shall include an appropriate period 
during which the ambient air shall be monitored to determine the impact 
of fugitive emissions of sulfur dioxide, arsenic (at copper smelters 
only), lead (at lead and zinc smelters only), and total suspended 
particulates on the ambient air quality in the smelter's DLA.
