Sherry- Yes, silver is a regulated metal, D011 and the level is 5 mg/l. I believe the "heavy" part is just a commonly used name, not really a regulatory term. You won't find silver in the F (wastes from non-specific sources) or K (wastes from specific sources) lists since it is a leachable metal and therefore it is listed separately with other metals and organics that exhibit a "toxicity characteristic". Copper is not regulated under RCRA but is regulated under CWA (Clean Water Act) due to its toxicity to aquatic life. Now, figure out why, if it is toxic to aquatic life, that it is not listed with other "toxicity characteristic" metals. Steve Noble Environmental Manager Photo Marketing Association International
