The purpose of this memorandum is to modify the Headquarters concurrence requirements for removal actions addressing certain residential mercury contamination. It anticipated that most future mercury-removals will continue to consist of individualized, small scale actions (such as those related to mercury theft and transport to the home from school buildings). Today's policy should be used in these instances. Larger-scale or unique mercury removal actions or mercury removal actions with the potential to substantially impact Regional or national budgets for removal should continue to follow the previous, formal concurrence processes.
