Total Maximum Daily Loads (TMDLs)

Answer: Pollutants levels arriving from the land area that drains to the waterbody are too high and need to be reduced to a “healthy” quantity.

Answer: A TMDL Look-Up Tool is available that allows the user to quickly identify if an approved TMDL is associated with surface waters within or bordering their municipality.

Answer: A TMDL is "proposed" when the Department publishes the TMDL Report as a proposed Water Quality Management Plan (WQMP) amendment in the New Jersey Register (NJR) for public review and comment. Following the public comment period, the Department prepares a response to comments and any required revisions to the TMDL. The revised document with response to comments is “established” upon submittal to EPA for review. Following EPA’s review and approval process, the TMDL is deemed “approved” and can then be “adopted” as an amendment to the WQMP.

Answer: When wasteload allocations are assigned to wastewater treatment plants, the permittee is assigned effluent limits that are consistent with the TMDL upon permit renewal. Non-regulatory measures include best practices for agricultural land use, riparian restoration, and promoting watershed stewardship activities such as rain gardens and rain barrels.

Answer: Public participation, by stakeholders, is a valuable part of TMDL development and can be beneficial at various stages throughout the process. For example, local knowledge of water quality conditions and/or potential pollutant sources can influence TMDL monitoring designs. In addition, local water monitoring data can assist in developing a more accurate water quality model. Stakeholder input during the TMDL publication phase can help refine the final report as well as identify appropriate fixes to improve and restore water quality.
