RE: Notice of Intent (NOI) for Puerto Rico Small MS4 NPDES General PermitJuncos' Pueblo Urbanized AreaJuncos Municipality, Commonwealth of Puerto Rico

Dear Mr. Soderberg:

On July 10, 2007, the Municipality of Juncos received a request of information fromthe Environmental Protection Agency (EPA) requesting the submission of a Notice ofIntent (NOI) for a National Pollutant Discharge Elimination System (NPDES) GeneralPermit. The Juncos Municipality has a Small Municipal Separate Storm SewerSystem (MS4) operating for many years that discharges storm water mainly to theValenciano River and the Gurabo River. The Juncos municipality is located within theSouth-East San Juan urbanized area as detennined by the EP A based on the latestDecennial Census (year 2000) by the Bureau of Census. Juncos is a municipalitywith a population of less than 100,000 persons. On January 9, 1998, EPAestablished in the proposed rule for the Commonwealth of Puerto Rico that forMS4s that are located within an urbanized area and the municipality haspopulation of less than 100,000, only the Pueblo will be regulated. Based on thisruling and the urbanized area map prepared by the EPA for the JuncosMunicipality, the Juncos' Pueblo Urbanized Area (JPUA) covered by the NPDESGeneral Permit is shown on the maps in Appendix 1.

After review of six (6) Environmental Impact Statement documents (see copies ofthe front page of the EIS documents reviewed in Appendix # 2) for projects inproximity to the JPUAU where the effects on listed endangered or threatenedspecies and critical habitats have been evaluated, there is no reason to believethat the storm water discharges, allowable non-storm water discharges anddischarge related activities will jeopardize the continued existence of any speciesor result in the adverse modification or destruction of critical habitat. Also, basedon this evaluation, there is no reason to believe that there are suitable habitatsfor these species within the JPUA.

In addition, after review of six (6) Environmental Impact Statement documents(see copies of the front page of the EIS documents reviewed in Appendix # 2) forprojects in proximity to the JPUAU where compliance with the National HistoricPreservation Act have been evaluated, there is no reason to believe that thestorm water discharges, allowable non-storm water discharges and dischargerelated activities will affect a property that is listed or is eligible for listing on theNational Register of Historic Places as maintained by the Secretary of theInterior.

As required by EPA and to be authorized to discharge storm water from a smallMS4, the Municipality of Juncos submits a notice of intent (NO I) and adescription of their storm water management program that currently is beingdeveloped (see NOI in Appendix # 3).

Sincerely,
