Description

This document provides the technical support for recommended maximum concentrations for 12 metals of environmental concern in land-managed exploration and production waste. The guidance values for arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc were adopted directly from the EPAs regulations for the land application of sewage sludge. EPAs risk-based approach was used to calculate values for barium and boron which were not addressed by the sewage sludge regulations. General guidelines for sampling and analysis of metals are also provided. Also, formulae for calculating the application rate for exploration and production (E&P) wastes containing metals are included. A comparison of these guidance values with metals concentrations from three E&P waste databases indicated that E&P wastes do not generally have levels of metals that are of environmental concern.
