Looking forward
• Promote “best practices”– range operations:
– Jacketed or lead-free ammunition– Lead-free primers – Replace sand berms with solid bullet traps
(with proper disposal of sand!)– Adequate ventilation, tested regularly– Clean range surfaces daily - with confirmation
sampling– Routine BLL testing of employees, regardless
of air lead levels. Medical removal at 10 ug/dL

How to manage the vent filters?

What they are told
• The filters may be classified as hazardous waste• If the TCLP results are less than 5 parts per million (ppm), the
filters can be disposed of as normal solid waste (trash). • Lead captured by the filter may be recycled. Recycling
activities are exempt from RCRA regulations. • Q: Is there a contact person at EPA that can offer guidance on
disposal if inventory is determined to be hazardous?A: For further assistance in understanding the applicable hazardous waste regulations, the generator should contact the hazardous waste agency in his or her state or the EPA Regional office
