| (6) If there are any changes to the composting or mulching
operation that would reclassify it from a registration operation to
a permit operation as authorized under §332.3 of this title,
the operation shall obtain an air quality standard permit for a permitted
composting operation.
(e) Permit operations. Composting operations required
to obtain a permit under §332.3(a) of this title that meet the
following requirements are entitled to an air quality standard permit.
(1) All permanent in-plant roads and vehicle work areas
shall be watered, treated with dust-suppressant chemicals, or paved
and cleaned as necessary to achieve maximum control of dust emissions.
Vehicular speeds on non-paved roads shall not exceed ten miles per
hour.
(2) Prior to receiving any material with a high odor
potential such as, but not limited to, dairy material feedstocks,
sewage sludge, meat, fish, oil and grease feedstocks, grease trap
waste, and municipal solid waste, the operator shall ensure that there
is an adequate volume of bulking material to blend with or cover the
material, and shall begin processing the material in a manner that
prevents nuisances.
(3) All material shall be conveyed mechanically, or
if conveyed pneumatically, the conveying air shall be vented to the
atmosphere through a fabric filter(s) having a maximum filtering velocity
of 4.0 ft/min with mechanical cleaning or 7.0 ft/min with air cleaning.
(4) Except for initial start-up and shut-down, the
receiving chamber on all grinders shall be adequately filled prior
to commencement of grinding and remain filled during grinding operations
to minimize emissions from the receiving chamber or grinding operations
shall occur inside an enclosed structure. In addition, all grinders
not enclosed inside a building shall be equipped with low-velocity
fog nozzles spaced to create a continuous fog curtain or the operator
shall have portable watering equipment available during the grinding
operation. These controls shall be utilized as necessary for maximum
control of dust when stockpiling ground material.
(5) All conveyors that off-load materials from grinders
at a point that is not enclosed inside a building shall have available
a water or mechanical dust suppression system. These controls shall
be utilized as necessary for maximum control of dust when stockpiling
ground material.
(6) All activities that could result in increased odor
emissions such as turning of compost piles shall be conducted in a
manner that does not create nuisance conditions or shall only be conducted
inside a building maintained under negative pressure and controlled
with a chemical oxidation scrubbing system or bio filter system.
