109. EMISSIONS LIMITATIONS - NEW PLANT:  The owner or operator of  a new lime manufacturing plant shall not permit, cause, suffer or allow emissions of particulate matter to the atmosphere to: 

     A.   Exceed 0.30 pounds per ton of limestone feed, or exhibit ten percent opacity or greater, from any lime kiln; or

     B.   Exceed 0.15 pounds per ton of lime feed to any lime hydrator. [11-30-95]
