LTMP Review
The LTMP is being conducted at the proper locations and frequencies.
Industrial User Permit (IUP) File Review
A review of the files for Hospitality Mints (#0003) and Charleston Forge (#0004) revealed that
the monitoring data was well organized and the slug control plans were in good order.
Industrial Inspection
Charleston Forge is a metal furniture manufacturer that has a categorical waste stream
regulated under 40 CFR 433.17. The inspection included a thorough review of the plant, sampling
practices, and industry self -monitoring.
The pretreatment audit is satisfactory. The program is being implemented in an excellent
manner. If you should have any questions, please do not hesitate to contact Paul DiMatteo at (336) 776-
