Enclosure 2020Annual Environmental Operating Report I. INTRODUCTION Palo Verde Nuclear Generating Station (PVNGS) islocated inMaricopa County, Arizona, approximately 50 miles westofthePhoenix metropolitan area The PVNGS site comprises approximately 4,250acres. Site elevations range from 890 feet above meansealevel atthesouthern boundary to1,030 feet abovemean sealevel atthenorthern boundary. Thestation consists of three pressurized water reactor electrical generating units. Units 1,2,and3 havea rated thermal power of3,990 MW.

Arizona Public Service (APS) Company wasissued lowpoweroperating licenses NPF-34, NPF-46 and NPF-65 for Units 1,2,and3 bytheUnited States Nuclear Regulatory Commission (NRC) on December 31,1984, December 9,1985, andMarch 25, 1987,respectively.

The principal objectives oftheEPPareasfollows:

(1) Verify that thestation isoperated inanenvironmentally acceptable manner, asestablished bythefinal environmental statement (FES) andother NRCenvironmental impact assessments.

(2) Coordinate NRCrequirements andmaintain consistency withother federal, state andlocal requirements forenvironmental protection.

B. Terrestrial Ecology Monitoring Section 4.2.2 oftheEPPstates that APSwill implement a salt deposition and impact monitoring program as communicated ina letter totheNRCdated December 30,1991(Reference 1), thesalt deposition monitoring program wasdiscontinued attheendof1991.

III. PLANT DESIGNAND OPERATION CHANGES Section 3.1oftheEPPallows changes instation design, operation, orthe performance oftests orexperiments affecting the environment provided that suchchanges, tests, orexperiments donotinvolve an unreviewed environmental question anddonotinvolve a change to theEPP.Changes, tests, orexperiments inwhich allmeasurable non-radiological effects are confined totheonsite areas previously disturbed during site preparation and plant construction orinwhich theenvironment isnotaffected areexempt fromtheevaluation andreporting requirements ofSection 3.1 Section 3.2oftheEPPalso exempts changes, tests, orexperiments which arerequired tocomply with other federal, state, orlocal environmental regulations.
