Sec. 60.423  Monitoring of operations.

    (a) The owner or operator of any ammonium sulfate manufacturing 
plant subject to the provisions of this subpart shall install, 
calibrate, maintain, and operate flow monitoring devices which can be 
used to determine the mass flow of ammonium sulfate feed material 
streams to the process. The flow monitoring device shall have an 
accuracy of 5 percent over its range. However, if 
the plant uses weigh scales of the same accuracy to directly measure 
production rate of ammonium sulfate, the use of flow monitoring devices 
is not required.
    (b) The owner or operator of any ammonium sulfate manufacturing 
plant subject to the provisions of this subpart shall install, 
calibrate, maintain, and operate a monitoring device which continuously 
measures and permanently records the total pressure drop across the 
emission control system. The monitoring device shall have an accuracy of 
5 percent over its operating range.
