|General Site Description:||
The Johnson Creek Complex site straddles the Multnomah and Clackamas County line. The Portland Building has the 4600 SE Harney Drive Address and is located in Portland on the Multnomah County side of the line. The Titanium Building has a Milwaukie address (5001 SE Johnson Creek Blvd.), and is located in Clackamas County.
The complex is in a mixed industrial/residential area. The site is either entirely paved or covered by buildings. Johnson Creek is located 500 feet south of the site. Shallow groundwater is 18 feet below the surface at the site. Deeper groundwater is used extensively in the area for drinking water - there are several City of Milwaukie municipal drinking water supply wells less than 1 mile south of the site.
The site is located along a relatively steep incline to its north which levels off as you approach Johnson Creek Blvd to the south.
|Site History:||(7/10/06 CWH/SAP) PCC Structurals, Inc., originally known as the Precision Castparts Corporation (PCC), was incorporated in 1956 and has been operating at this site, referred to as the Johnson Creek Complex, since 1957. The Portland Building (also known as the Large Structurals Business Operation, or LSBO) was built in 1957. The Titanium Building (also known as the Titanium Business Operation, or TBO), was constructed in 1949-50 by the Oregon Saw Chain Corporationfor manufacturing saw chains. During the 1970's the TBO was owned by Ford Industries, Inc., and occupied by Cod-A-Phone, which manufactured electronic communications equipment, including answering mahcines. PCC purchased the TBO building in 1981. The Neutralization Building was constructed by PCC in 1986-87 for on-site hazardous waste neutralization and recycling operations.|
(5/24/95 KPD/SRS) The Precision Castparts Corporation (PCC) manufactures parts and components from various alloys using an investment casting process. Stainless steel parts are produced in the Portland Building, while titanium parts are produced in the Titanium Building. Various hazardous materials are used. Spent solutions of nitric and hydrofluoric acids, and potassium and sodium hydroxides, are sent to an on-site Neutralization Building for pH adjustment, filtering, and discharge to the industrial sewer system under permit. Slightly radioactive thorium, used in the titanium casting process, is disposed of at Hanford, Washington. Solvents, including perchloroethylene (PCE) and trichloroethylene (TCE), are drummed and recycled off-site. As of 1993, the drums were stacked in storage areas that were outside, uncovered, and unbermed. Asphalt surfaces directed spills and runoff to storm drains that discharged to Johnson Creek. Various releases are known to have occurred. In addition, PCE contamination has been intermittently observed in groundwater beneath the site. The source of this contamination is not known.
(7/10/06 CWH/SAP) An updated review and more recent groundwater sampling data show a clear trend in increasing concentrations of PCE at the site (See Figure 3 presented in Image 3). PCE has been measured at 15.6 ppb in Well #2 in April 2003 - well above EPA drinking water MCL of 5 ppb, EPA Region 9 Preliminary Remediation Goal (PRG) for tap water of 0.1 ppb.
During groundwater sampling of Well #2, trichloroethene (TCE) was detected for the first time at a concentration of 1.67 ppb. The TCE concentration is below the EPA drinking water MCL of 5 ppb, but above DEQ Risk-Based Concentrations for protection of drinking water (0.029 ppb) and EPA Region 9 PRG for tap water of (0.028 ppb).
A single soil sample test result submitted to DEQ in March of 2006 that showed no detections of volatile organic compounds (VOCs) is not considered relevant for several reasons: (a) details of the soil sample location were missing; (b) laboratory detection limits were above several relevant DEQ risk-based soil concentration levels for protection of groundwater.
Overall trend of data since 1996 is increases in chlorinated solvents in groundwater below the PCC-JCC site. PCE and TCE have been used at this site for many years.
A review of DEQ Water Quality Stormwater sampling records shows that stormwater discharge at the PCC-JCC site has exceeded (non-enforceable) benchmarks established for zinc. Concentrations of zinc measured in Johnson Creek sediments near the PCC-JCC site showed local increases, relative to upstream concentrations at the discharge point that serves the sites southern boundary and the main storm outlet located east of the site.
|Manner and Time of Release:||
Discharge of wastes (through spills, overflows, etc.) down storm drains to Johnson Creek. Time of Release: occasional; known to have occurred at least once per year from 1987 to 1992.
(7/10/06 CWH/SAP) Summary of Hazardous Waste inspection problems:
(a) DEQ RCRA inspection in January 1986 - Inspectors found numerous drums of hazardous waste that were being stored outside for more than 90 days. Addressed by (then) Precision Castparts in November 1986.
(b) DEQ RCRA Compliance inspections in Dec. 1986 and Feb. 1987 - Inspectors found improper storage of waste oil containers, some of which caused a discharge to Johnson Creek via storm sewers.
(c) DEQ RCRA compliance inspection in Nov. 1987 - Additional rule violations were noted, including storing hazardous wastes for more than 90 days; mislabelling hazardous waste storage containers, and discharging cooling water contaminated with ethylene glycol into the storm sewer.
(d) In February 1992 a Multi-Media Compliance Inspection was performed at the site by EPA's Oregon Operations Office under the Federal RCRA program. The inspection focused on PCC's use and disposal of regulated hazardous wastes. The inspection found numerous violations, including unlabelled storage containers, improper storage, incorrect shipping manifests, and a lack of documentation.
(e) PCC had been fined or cited for improper discharges to Johnson Creek at least once a year from 1987 to 1991.
In February of 1990, DEQ performed sampling at the site as part of an NPDES (National Pollutant Discharge Elimination System) permit monitoring report. DEQ sampled PCC's cooling water discharge to Johnson Creek (which enters the creek through the storm sewer outfall), above and below the outfall. Samples were analyzed by EPA Method 8240 for volatile organic compounds (VOCs). PCE was detected in the cooling water discharge at up to 11 ppb. PCE was also detected in Johnson Creek below the storm outfall at 5 ppb and was not detected in Johnson Creek above the outfall.
|Hazardous Substances/Waste Types:||
PCE, TCE, Freon-113, potassium and sodium hydroxides, hydrofluoric and nitric acids, thorium.
(7/10/06 CWH/SAP) In October 1989 PCC responded to a DEQ information request on their use of solvents. PCC reported using 200,000 lbs per year of TCE, 18,000 lbs. per year of PCE, and 6,500 lbs pery of 1,1,1-trichloroethene (TCA). TCE had been used since about 1975, PCE since about 1968, and TCA since about 1979.
|Pathways:||The Johnson Creek Complex is in a mixed industrial/residential area. Johnson Creek is located 500 feet south of the site. The creek is used to a limited extent for irrigation and as a source for industrial process water. Shallow groundwater is 18 feet below the surface at the site. Deeper groundwater is used extensively in the area for drinking.|
|Status of Investigative or Remedial Action:||
(5/24/95 KPD/SRS) Groundwater at the site has fluctuated between having no detectable levels of contamination, and having contamination at twice the federal MCLs. Soils at the site have not been sampled. Considering the long history of on-site operations, the large amounts of hazardous substances used at the site, and Precision Castparts' record of poor waste-management practices, SRS feels that this site is a medium priority for further agency action. An expanded Preliminary Assessment (XPA) should be performed to collect additional soil, groundwater, and sediment samples, plus additional information on hazardous substance use, storage, and disposal practices. The XPA should either be performed by Precision Castparts under the supervision of the Voluntary Cleanup Program (VCP), or by DEQ's Site Assessment Program.
(7/10/06 CWH/SAP) DEQ performed an updated evaluation of the PCC Structurals, Inc. - Johnson Creek Complex (PCC-JCC) site. As part of this evaluation DEQ received additional groundwater well testing data that showed a continuing increase in perchloroethylene (PCE) concentrations in groundwater below the PCC operation. Between June 1996 and April 2003, PCE concentrations in groundwater below the site have increased from 2 parts-per-billion (ppb) to 15.7 ppb. These concentrations are well above the Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL) for drinking water of 5 ppb and the EPA Region 9 Preliminary Remediation Goal (PRG) for cleanup of groundwater used as drinking water of 0.1 ppb for PCE. While it is true that measured PCE concentrations have fluctuated somewhat over the period that sampling has occurred, the overall trend is a continuing increase.
In addition, the April 2003 sample results also detected trichloroethene (TCE) at 1.67 ppb in Well #2. This result is at a concentration that is below the EPA MCL of 5 ppb, but above the EPA PRG of 0.028 ppb.
In response to this evaluation PCC-JCC submitted laboratory results for a single soil sample that was tested in November 2005. No details of the area where the soil sample was acquired was provided. The laboratory results for the soil sample was all non-detects for volatile organic compounds (VOCs). However, it should be noted that the detection limits for the November 2005 soil tests for PCE (99.5 ppb) and TCE (99.5 ppb) are above DEQ's risk-based concentrations for leaching to groundwater for protection of residential drinking water sources of 5.3 ppb for PCE and 0.48 ppb for TCE.
There are several factors that would point to PCC-JCC as a probable source of the detected PCE - (a) PCC's casting process has long incorporated the use of PCE and TCE; (b) The PCC-JCC site has a past record of poor waste management and spills; (c) A current soil and groundwater investigation of the PCC plant on SE 84th Avenue in Clackamas (ECSI #1617) - an operation similar to the PCC-JCC plant - has found high concentrations of chlorinated solvents in groundwater; (d) There are no other major manufacturing operations near the PCC-JCC site that are likely sources of PCE and TCE contamination.
PCC-JCC stormwater sampling data also indicates that it may be a source of zinc discharges to Johnson Creek. Recent sampling of Johnson Creek sediments indicate local increases of zinc in sediment at outfalls that service the PCC-JCC property and facilities.
(a) The PCC Structurals, Inc. - Johnson Creek Complex site is located in close proximity to the City of Milwaukie's drinking water aquifer and residential areas. Chlorinated solvent contamination that exceeds risk-based standards for protection of human health have been measured in PCC-JCC wells. Concentrations of PCE measured in groundwater have been increasing steadily over time.
(b) A Site Investigation (SI) is required at the PCC-JCC site to determine if it is a source of PCE contamination. Given that the PCE concentrations in groundwater below the PCC-JCC site exceed risk-based screening criterion, further action is considered to be a high priority.
(c) Further investigation of possible sources of zinc contamination to Johnson Creek from the PCC-JCC site should be performed.
(11/6/08 SM/SRS) PCC entered into an agreement on September 9, 2008 with DEQ to conduct a Remedial Investigation (RI) to assess whether chlorinated solvent contamination exists in soil and groundwater at the JCC. PCC will submit an RI proposal to DEQ by November 14, 2008.
