Te Tar–Pamlico Basin Association (TPBA) currently has 16 members representing 20 dis- charge facilities that account for 98% of the known efuent fow to the basin. Te remain- ing 2% of efuent fow is from 18 small facilities that have permit limits based on their size and capability. All National Pollutant Discharge Elimination System (NPDES) permitted facilities use 7Q10 standards (the lowest stream fow for seven consecutive days that would be expected to occur once in 10 years) as critical fow in determining permit limits for non-carcinogen toxicants (EPA 2013b) . Low-fow conditions impact the ability of a stream to assimilate both point and nonpoint source pollutants. Droughts, as well as the demand on water resources, are likely to increase; therefore, the reevaluation of stream fow will become more critical to water quality in the future (NCDWR 2015d) . Te progress achieved by the agriculture sector in implementing the Tar–Pamlico Agriculture Nutrient Control Strategy Rule is well documented in the Annual Agricultural Progress Reports submitted to the NCDENR Environmental Management Commission (EMC) every fall since 2003. As of 2002, the agriculture sector exceeded its collective 30%
