I Dear EPA Representative, Shieldon Industries respectfully requests an exemption from the "Primary Copper Smelting: National Emissions Standards for I Iazardous Air Pollutants (NEST TAP)" regulation, citing unique circumstances that impact our ability to comply. While we fully support efforts to protect air quality and public health, our operations face significant technical and financial constraints that make adherence to certain provisions of the regulation unfeasible. Shieldon Industries has implemented robust emission control technologies and remains committed to minimizing our environmental footprint. However, the compliance requirements of NEST TAP impose challenges that jeopardize our ongoing viability and contributions to the local economy. We kindly ask the EPA Sierra Club FOIA 2025-EPA-04883 ED_018388_00005755-00001 SC_EVERSPLIT0020594 to consider this request in light of our proactive measures and willingness to collaborate on alternative solutions to achieve mutual goals. If you have any further questions regarding this matter, you can reach me at : Ex 6 Personal Privacy (PP) d I can provide any further information at your convenience.
