The USWAG Interpretative Letter Compendium offers important EPA guidance that is not available elsewhere. This collection of over 100 key EPA PCB interpretive letters discusses a broad array of PCB compliance matters. These letters - which contain important Agency guidance on PCB regulatory issues - are not available on any of EPA's various web sites and therefore are not readily available to the public. This collection offers important guidance for reducing regulatory costs and facilitating compliance with applicable PCB regulations.
