1. INTRODUCTION As part of its application for a certificate of compliance. Title 10 Code of Federal Regulations (CFR) Part 76.35(g) requires that United States Enrichment Corporation (USEC) provide an environmental compliance status report describing the status of Federal, State, and local environmental permits, licenses, approvals, and other entitlement, as well as the compliance status with applicable environmental quality standards and requirements described in 10 CFR 51.45(d) that are applicable to USEC operations. In addition,10 CFR 76.35(g) requires that the compliance status report contain current environmental and effluent monitoring data. This report covers the compliance status of PGDP l

with applicable Federal, State, and local permits, licenses and other er.titlements through the end of l

calendar year (CY) 1997. Due to the required schedule for submission of this document, effluent and l

environmental data and the public dose assessments for CY 1997 will not be available in time for I

inclusion here. Consequently, the effluent and environmental data and dose assessments for CY 1996 l

are provided instead.

l

2. DESCRIPTION AND COMPLIANCE STATUS OF PERMITS, REGISTRATIONS, AND OTHER ENTITLEMENT, AND OTHER APPLICABLE ENVIRONMENTAL QUALITY STANDARDS AND REQUIREMENTS USEC is required to operate PGDP in compliance with a number of Federal and State environmental permits, registra: ions, other entitlement, and other applicable environmental quality standards and requirements. The following matrices (Tables 1 and 2) identify each of the environmental permits that govem USEC activities at the PGDP. They also identify the principal permit limits, provide a summary of monitoring and emissions / effluent data for each permit, and contain a nummary statement on the status of USEC compliance.

2.1 CLEAN AIR ACT Pursuant to the Federal Clean Air Act (CAA), as amended, and corresponding Commonwealth l

of Kentucky laws and regulations, USEC currently has the responsibility for several air permits issued j

by the Kentucky Division for Air Quality (KDAQ). The first one,0-110-85, was issued in September l

of 1985 to DOE. Based on the lease agreement, responsibility for a number of these points has been l

transferred to USEC. KDAQ will issue a new air permit for these sources during the Title V permitting I

process. Until the new Title V permi is issued, the permit conditions and limitations, contained in O-l t

110-85 remain in effect, unless a modification is needed before the Title V permit is issued.

l A second KDAQ permit, S-95-036, was issued to USEC on February 23,1995 for three sources.

l Two of these were existing and the third was a new source. This permit was necessitated by the addition l

1 l

l ECSR-PGDP April 15,1998

~

l Rev.24 of a new emission point, the C-335 surge drum purging vent. The two existing operations included in l

this permit are the C-310 cascade operations and the C-410-K fluorine manifold facility.

l In November of 1996, USEC submitted a skeleton plant-wide Title V air permit application.

l There were 9 operations that did not meet the insignificant or trivial activity criteria and will rec,uire l

specific detailed information on the full Title V submittal due by December 14, 1998. KDAQ has one l

year to issue a permit from this date. Many of the emission points that were included on previous l

applications and permits are excluded from detailed penaitting requirements because they fall into either l

the insignificar*

ivial activities categories. The terms insignificant and trivial are descriptive of the l

these act lities. There are some air emissions from these activities, but they are so l

b air emissiore (to inconsequential snat specific permit conditions and limitations are not required.

l USEC is in compliance with Federal regulations issued pursuant to the CAA that govern management of asbestos.

Finally, the PGDP Fire Services Section conducts its own fire training exercises on property leased by USEC from DOE. USEC is in compliance with KDAQ regulations governing open burning.

2.2 CLEAN WATER ACT USEC and DOE jointly hold a Kentucky Pollutant Discharge Elimmation System (KPDES) pemiit reissued pursuant to State laws and regulations and the Federal Water Pollution Control Act, as amended (conunonly referred to as the Clean Water Act [ CWA]). The permit was initially issued by the Kentucky Division of Water (KDOW) to DOE in September 1991, with an effective date of November 1,1992.

In June 1993, KDOW added USEC as a joint permittee of the KPDES permit.

The KPDES permit encompasses 18 outfalls discharging into two creeks. Fifteen of the outfalls l

were leased by USEC during the period of this report. The permit conditions for these outfalls are l

presented in Table 2. Of those 15, three of the outfalls are out of service and have no discharges.

l I

Three of the outfalls were retained by DOE.

l I

In 1997 two of the USEC-leased outfalls, outfalls 001 and 015, were de-leased r.nd transferred

[

back to DOE. These outfalls are included in Table 2 lxx:ause they were leased by USEC for the majority l

l of the report period.

l 2

ECSR-PGDP April 15,1998 Rev.24 In response to permit adjudication proceedings initiated b DOS, the Commonwealth of Kentucky l

/

in 1992 granted a stay of the KPDES permit limits for pH, metals, and temperature. As a result of this j

adjudication, an Agreed Order (AO) was exect:ted between DOE, USEC, and the Kentucky Natural l

Resources and Environmental Protection Cabinet. This AO sets interim limits for pH and temperature, l

requires reporting of monitoring results for metals (with no imposed limits), and establishes requirements l

to conduct studies for pH, temperature, and metals. Data from these studies will be used as basis for l

setting final limits for these parameters.

l l

Permit limits for USEC outfalls are summaiiz.ed in Table 2. Limits for metals were stayed as l

dismissed above. All other limits in the table were in effect.

l l

During 1996 and 1997 USEC was in compliance wi'h the permit lirr,ts with the following l

exceptions:

l I

j 1996 exceedar es:

2 fecal coliform Outfall 004 l

1 i suspended solids Outfall 006 l

1 residual chlorine Outfall 008 l

l 1997 exceedances:

I residual chlorine Outfall 008 l

2 suspended salids Outfall 006 l

1 l

Because the two chlorine exceedances (the first in December 1996 and the second in January l

1997) were recorded in consecutive quarterly monitoring periods, the KDOW determined a significant l

noncompliance occurred and issued a Notice of Violation (NOV) requiring a written response. These l

exceedances were due to pump failures at the sodium thiosulfate feed sution at the sewage treatmen:

l plant. This information was provided to the regulator and no funher action was required.

l Data on the discharge of radionuclides are provided below in Section 3 and 4. Information and l

I data on outfalls for which DOE is responsible are not included in this report.

l 1

2.3 RESOURCE CONSERVATION AND RECOVERY ACT Until April 1996, USEC and DOE jointly held a permit issued pursuant to the Resource l

Conservation und Recovery Act (RCRA), as amended, anu applicable Commonwealth laws and l

regulations promulgated thereunder, in April 1996, USEC was removed from the RCRA permit and was l

issued a separate generator identification number. DOE retained all of the responsibilities set forth in j

the permit.

l USEC generates hazardous and mixed waste, and complies with requirements for generators, l

including accumulation of waste in satellite accumulation areas and accumulation of waste in 90-day I

accumulation areas (90-DAAs). DOE operates the permitted treatment and storage facilities under the l

RCRA permit. USEC did not receive any NOVs for RCRA noncompliance during 1996 or 1997.

l 3

l l

ECSR-PGDP April 15,1998 Rev.24 USEC is currently shipping the majority of USEC-generated hazardous and mixed waste directly l

from 90 F Ms to offsite treatment, storage, and disposal (TSD) facilities. Until treatment facilities are l

found foi all mixed wastes some USEC mixed waste will be sent to DOE-operated storage units.

l l

An AO between USEC and the Kentucky Natural Resources and Environmental Protection l

Cabinet became effective on November 15,1995. This AO establishes requirements for the management l

Of mixed waste. During 1996 USEC was in compliance with all requirements of the AO. In 1997 there l

was one USEC noncompliance with a requirement to notify the Cabinet upon completion of a milestone l

or deadline in the AO.

l 2.4 STORAGE TANKS USEC operates two fuel underground storage tanks (USTs). The tanks are registered under and in compliance with Kentucky Department of Environmental Protection regulations governing USTs.

l USEC also operates 40 aboveground tanks, including 3 large fuel oil tanks and various smaller tanks holding gaso!ine, diesel fuel, kerosene, and transformer oil. A Spill Prevention, Countermeasures, and Control Plan has been submitted to the United States Environmental Protection Agency (USEPA) and KDOW for these tanks pursuant to the CWA, and a Facility Response Plan has been submitted pursuant to the Oil Pollution Act of 1990.

2.5 POLYCHLORINATED BIPHENYLS USEC leases transformers and capacitors from DOE that contain greater than 50 parts per million (ppm) PCBs. Matters regarding the management of equipment, as well as the storage, disposal, and attention to past spills of PCBs are the responsibility of DOE pursuant to the lease agreement betwegn DOE and USEC.

2.6 EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT; RELEASE REPORTING LNDER THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT USEC is in complixnce with requirements of the Emergency Planning and Community Right-to-Know Act (EPCRA), including the preparation of an emergency response plan under Section 302, hazardous chemical reportog under Sections 311 and 312, and toxic chemical release reporting under Section 313. In ddition, USEC is in compliance with release reporting requirements for reportable quantities of hazardous substances under Section 103 of the Col'prehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended.

3. NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS (NESHAPS) l l

Under the requirements of 10 CFR 61 (NESHAPS) Subpart H, emissions of radionuclides to the ambient air from DOE facilities must not exceed those amounts that would cause any member of the public to receive an effective dose equivalent (EDE) of 10 mrem / year in any year. In January 1992, DOE and EPA fmalized a compliance plan setting forth the process by which PGDP would demonstrate compliance with the NESHAPS standards.

In 1996, as result of both USEC and DOE operations at PGDP, the calculated effective dose j

equivalent (EDE) due to airborne radionuclides emissions for the maximally exposed individual located j

approxinutely 1,100 meters north of the nonh side of the plant security fence was 0.0053 mrem. Off-site l

ambient air samples obtained during 1996 did not indicate the presence of any significant contamination l

above normal levels.

I l

The calculated CEDE from a:rhorne releases was 0.05 person-rem.

l

4. ENVIRONMENTAL MONITORING DATA In addition to the data required by environmental permits and regulations, USEC monitored environmental media for the purpose of identifying possible effects of plant emissions on the surrou iding area. The activities included ambient air, soil, and sediment sampling, sampling of locally grown food crops, monitoring of direct radiation from plant sources, and monitoring of radionuclides discharges beyond those required by the KPDES permit. The data obtained from this program during 1996 are j

summarized in Tables 5 through 11.
