I have noticed small white “DEP file number” signs posted at various locations, often where construction work is going on. Are these hazardous waste sites?
No. The signs mark locations for which MassDEP’s Wetlands Program has issued file numbers for the purpose of tracking projects approved by local conservation commissions. No work proposed for a wetland area or within a 100-foot radius may proceed before a local order of conditions has been issued. Separately, DEP’s Bureau of Waste Site Cleanup assigns tracking numbers to confirmed and suspected hazardous waste sites across the state.
