What is the Nitrogen and Selenium Management Program (NSMP)?
Order No. R8-2004-0021 for the Newport Bay watershed includes numeric effluent limits that may be difficult or impossible to meet since there are no feasible treatment technologies for selenium for short-term groundwater-related discharges. To recognize this problem, the permit allows for an alternative compliance approach that consists of implementing a Work Plan to investigate selenium and nitrogen sources and impacts as well as potential treatment or reduction methods. The NSMP is the effort by a stakeholder Working Group to implement this Work Plan.
