Wood Working Operations

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.

  • 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 Section 112.
  • 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 Operations:

  • 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.
