section shall not be in effect until June 1, 1977 for the   equipment
located in Buildings 425 and 426 provided the following conditions are
fully met:      
   
               (A) The following increments of progress are met      
and promptly reported as such increments relate to the installation of
equipment which will enable attainment of the    
limitations of this subsection:      
   
   
   


          ACTION      DATE  
---------------------------------------------------------------      
     (1) Date of submittal of        
the source's final control plan              March 1, 1975            
to the Department of Pollution      
Control and Ecology;                
   
     (2) Date by which contracts    
for emission control systems or      
process modification will be awarded;            
or date by which orders will be               July 1, 1975            
issued for the purchase of component
parts to accomplish emission control
or process  modification;            
   
     (3) Date of initiation of on-site          
construction or installation of emission     October 1, 1975          
control equipment or process change;
   
     (4) Date by which on-site      
construction or installation of              January 1, 1977          
emission control equipment or process            
modification is to be completed;    
   
     (5) Commencement date operation of          
source with emission control system in       March 1, 1977            
place and functioning; and          
   
     (6) Date by which full and final            
compliance is achieved, which compliance        
is recognized by the filing of a             June 1, 1977            
certificate of compliance with the  
Department and which certificate    
is based upon a sampling program    
approved by the Commission.          
   
   
               (B) The equipment utilization, on annual average, does
not exceed the percent  utilization given for each piece of equipment
as described above under CSN 630010. For purposes of                  
this regulation, annual equipment utilization for similar pieces of  
equipment serving parallel processes located in the same building and
having  identical allowable emission rates, may be                    
determined by computing an equivalent annual average. An equivalent  
annual average is computed by summing the number of hours which each  
of (N)  similar pieces of equipment is operated during a year and    
dividing that sum by the product of (N) and 8,760 hours. The owner or
operator of the equipment affected by this requirement shall maintain
such records as may be necessary to assure the Director that the      
equipment utilization rates as provided above are not exceeded.      
   
               (C) The requirements of Subsection (B) above shall be  
rescinded upon full attainment  of the emission limitations provided  
above for the equipment in Buildings 425 and 426.

     (ii) Stone Quarrying and Crushing Operations

       (A) The requirements of this subsection shall apply to limestone and crushing operations having a primary crushing capacity of 300 tons per hour and to all other stone  quarrying and crushing operations having a primary crushing capacity of 500 tons per hour.  

       (B) Prior to September 1, 1975, owners and operators of quarrying and crushing operations affected by the provisions of this subsection shall notify the Department in writing as to the location of said quarrying and crushing operations and shall describe the nature of the operation, the capacity of the equipment used at said location, and the nature and estimated efficiency of air pollution control techniques employed at said location.
       (C) No person shall cause or permit the operation of a quarrying and crushing operation affected by the provisions of this subsection in a manner which would allow excessive and unnecessary amount of particulate matter to become airborne. For purposes of this requirement, wet sprays on the inlets and outlets of crushers, or equivalent controls, shall be considered minimal controls necessary to prevent unnecessary amounts of particulate matter from becoming airborne. No quarrying or crushing facility shall be permitted to operate in a manner which would cause visible emissions to extend beyond the property line of the affected facility or which would interfere with the attainment and maintenance of the National Ambient Air Quality Standards.

     (iii) Rice and Soybean Processing Facilities

       (A) The requirements of this section shall apply to facilities known as rice mills and soybean processing plants. It is not intended that these regulations apply to facilities designed for the drying and storage of rough rice or soybeans.

       (B) No person shall cause or permit the operation of facilities affected by the provisions of this subsection in a manner which would allow the emission of particulate matter from said facilities to exceed 1.5 pound for each ton of rice or soybeans processed.

     (iv) Asphalt (Mix) Concrete Plants

       (A) No person shall cause or permit the operation of an asphalt concrete plant, constructed or modified after June 11, 1973, to exceed the Standards of Performance for New Stationary Sources (40 CFR 60.90) as promulgated by the United States Environmental Protection Agency.

       (B) After June 1, 1976, no person shall cause or permit the operation of an asphalt concrete plant, constructed or modified prior to June 11, 1973, except as specified herein. Prior to commencement of operation at any location, the owner or operator shall notify the Director in writing of the location of the asphalt concrete plant, stating the capacity of the plant, the control equipment to be used and the expected rate of emissions. Upon receipt of such notification, the Director may authorize the operation as proposed by said owner or operator or may require, where the plant is proposed to be operated in areas of high population density or areas in which the National Ambient Air Quality Standards are threatened, more stringent controls than proposed by said owner or operator. In no case, however, shall the Director approve or authorize the operation of an asphalt plant from which the emissions exceed 100 lbs/hr or 1000 lbs/day.

       (C) Routine maintenance, repair and replacement, relocation of a portable plant, change of aggregate, and transfer of ownership are not considered modifications which would require a plant which was constructed prior to June 11, 1973 to comply with the provisions of Subsection (A) of this section.

       (D) Portable asphalt concrete plants which relocate after June 30, 1975 shall, upon said relocations, comply fully with the provisions of Subsection (B) of this subsection.

       (E) Except as provided by the provision of Subsection (B) of this subsection, portable asphalt concrete plants which were constructed or modified prior to June 11, 1973 shall not be affected by the visible emission limitations of the Regulations of the Plan.
