What are local limits?
Local limits are wastewater limitations that apply to commercial and industrial facilities that discharge to a publicly owned treatment works (POTW). Local limits are developed to meet the pretreatment program objectives and site-specific needs of the local POTW and the receiving stream.

Local limits control the pollutants in the wastewater discharges from commercial and industrial facilities and apply at the "end-of-pipe" from the facility. The regulations under 40 CFR §403.5 (d) give the POTW the authority to enforce its local limits.
