[Code of Federal Regulations] [Title 40, Volume 27] [Revised as ofJuly 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR464.14] [Page 560-562] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 464--METAL MOLDING AND CASTING POINT SOURCE CATEGORY--Table of Contents Subpart A--Aluminum Casting Subcategory Sec. 464.14 New source performance standards. Any new source subject to this subpart must achieve the following new source performance standards (NSPS), except that non-continuous dischargers shall not be subject to the maximum day and maximum for monthly average mass (kg/1,000 kkg or lb/million lb of metal poured; kg/ 62.3 million Sm3 or lb/billion SCF of air scrubbed) effluent standards for copper, lead, zinc, total phenols, oil and grease, and TSS. For non-continuous dischargers, annual average mass standards and maximum day and maximum for monthly average concentration (mg/l) standards shall apply. Concentration standards and annual average mass standards shall only apply to non-continuous dischargers. (a) Casting Cleaning Operations.
