Wood Working Operations
Wood working operation means any operation involving the generation of small wood waste particles
(shavings, sanderdust, sawdust, etc.) by any kind of mechanical manipulation of wood or wood byproducts. It
includes, but is not limited to, sawing, planing, chipping, shaping, moulding, hogging, lathing and sanding and all
applicable control devices such as baghouses, cyclones, and portable dust collectors or any internal combustion
engines that may be used to power the wood working equipment. Additionally, it covers any wood working waste
transfer or collection units such as silos, cyclones, trailers, conveyors, etc. Some wood working facilities also
conduct surface finishing. This permit also covers the surface finishing of woods and all applicable finishing
materials, control devices such as paint booth filters, cartridges, etc, and dryers, burn-off and curing ovens that
may be used during the drying process. Sources that conduct onsite lumber or chip drying prior to machining can not
be permitted under this registration permit.
List of Wood Working Operations
covered by a Registration Permit
- Sources can only be fired on natural gas, propane, virgin No. 2 fuel oil, virgin diesel, Biodiesel that meets
ASTM D6751or any other Department approved fuels. The use of any non-specification oil, hazardous waste, or any
other waste chemical as a fuel or any addition of these items to the fuel shall not be allowed. External
combustion sources shall be fired on low sulfur (0.05 wt% or less) diesel/No. 2 fuel oil and the diesel engines
shall be fired on ultra low sulfur (0.0015 wt% or less) diesel.
- The maximum size for a single external combustion source burning fuels other than natural gas and propane is
limited to 20 million BTU/hr heat input capacity.
- The maximum size for a single internal combustion source burning fuels other than natural gas and propane is
limited to 600 hp mechanical power output and a displacement of <10 liters per cylinder.
- Facility wide potential to emit is less than any major source thresholds as defined in Title V, NSR, PSD, and
- Option A: Use less than 2667 gallons per 12 month period of HAP containing materials used for surface coatings,
touchup and repairs, washoff operations, cleaning, and any other surface finishing materials containing HAP
Option B: Facility-wide HAP emissions of less than 10 tons of any one hazardous air pollutant and less than 25
tons of any combination of hazardous air pollutants per 12-month periods.
The following wood working tools are exempt from the requirement to obtain a construction permit.
However, they are subject to the applicable conditions as outlined in the Registration Permit for Wood Working
- Hand Sanders
- Hand Saws (chain saw, hand drills, etc.)
- Hand Distressing Tools (chisel, etc.)
- Equipment used for boring, notching, etc.
If the operations covered by construction permits are located in one of the eight coastal counties of
the Coastal Zone under DHEC-OCRM's jurisdiction (Beaufort, Berkeley, Charleston, Colleton, Dorchester, Georgetown,
Horry and Jasper), then a coastal zone consistency certification may be required.
- Wood Working Emissions Estimator – Wood Waste:
Calculates PM, PM10, and PM2.5 emissions using the amount of waste collected and the capture efficiency of waste
- Wood Working Emissions Estimator - Wood
Throughput: Calculates PM, PM10, and PM2.5 emissions from wood working equipment based on process throughput
rates and emission factors.
- Wood Working Emission Estimator - Combustion:
Calculates PM, PM10, PM2.5, VOC and NOx emissions from combustion sources using AP-42 emission factors.
- Wood Working Emissions Estimator - Surface
Finishing: Calculates PM, PM10, PM2.5, VOC and HAP emissions from paints, solvents, glues, etc using a
- Wood Working Exemption
Determination: Flowchart that helps a facility determine if they are exempt from the requirements to obtain
a construction permit or if the Wood Working Registration Permit is needed.
