SUMMARY

The Puerto Rico Aqueduct and Sewer Authority (PRASA) has applied for
renewal of its National Pollutant Discharge Elimination System (NPDES)
permit for the Mai Paso Water Treatment Plant (WTP) in Penuelas.

The Mai Paso Water Treatment Plant (WTP) is a filtration plant that treats
water from the Guayanes Creek to provide clean drinking water to rural
sectors and residents of the Municipality of Penuelas. Wastewater from
the treatment plant is discharged to a tributary of Barreal Creek.

The NPDES permit ensures that the amount of discharge and the amount
of contaminants in the discharge remains below levels that are safe for
the environment and public health consumption.
