4 WASTEBED 13 SETTLEMENT PILOT STUDY MONITORING DATA YEAR 2 SECTION 1 PROJECT BACKGROUND 1.1 INTRODUCTION This Onondaga Lake Phase I Pre-Design Investigation: Monitoring Data Year 2 (Data Report) presents the second year of monitoring data (i.e., November 2006 through October 2007) from the Phase I Pre-Design Investigation (PDI) (Pilot Study). This monitoring was performed by Parsons on behalf of Honeywell International, Inc. (Honeywell) to support future Onondaga Lake remediation activities associated with requirements of the Consent Decree (United States District Court, Northern District of New York, 2007) (89-CV-815) that Honeywell entered into with the New York State Department of Environmental Conservations (NYSDEC). This monitoring was performed in accordance with the schedule proposed in the Onondaga Lake Pre-Design Investigation: Data Summary Report (Summary Report) prepared by Parsons and Geosyntec (2008). A major component of the NYSDEC s and United States Environmental Protection Agency s (USEPA) selected remedy for Onondaga Lake, as specified in the Record of Decision for the Onondaga Lake Bottom Subsite of the Onondaga Lake Superfund Site (NYSDEC and USEPA, 2005), includes the removal (i.e., dredging) and onsite consolidation of the majority of the removed sediments. Therefore, an onsite sediment consolidation area (SCA) is required. As discussed and concluded in the Onondaga Lake SCA Siting Evaluation (Parsons, 2006), Wastebed 13 is currently the recommended SCA location based on an evaluation of access considerations, capacity, current and future site use, geotechnical considerations, and potential community impacts. On the basis of this recommendation, several concurrent pre-design investigation activities were initiated, including the Pilot Study. Following this brief introduction, this section provides the site and Pilot Study background information, as well as the general organization for the remainder of this Report. 1.2 SITE AND PILOT STUDY BACKGROUND INFORMATION As indicated previously, the Pilot Study is located on Wastebed 13, which was originally designed as a settling basin for the disposal of Solvay waste, a by-product of sodium carbonate (soda ash) production via the Solvay process (i.e., process by which soda ash is formed from salt, limestone, carbon dioxide, and ammonia). Solvay waste is a combination of process residuals, unreacted material, and mineral salts that was deposited in a slurry. Solvay waste was produced by Honeywell s predecessor, Allied Chemical, between 1881 and 1986, and Wastebed 13 received the material from 1973 to Wastebed 13 is located in the Town of Camillus, Onondaga County, New York (Figure 1.1). Wastebed 13 occupies approximately 163 acres and is bordered to the north by Ninemile Creek and CSX Railroad tracks; to the west by an Onondaga County Garage property, a former gravel P:\Honeywell -SYR\ SCA FFS\09 Reports\2007 Summary Report\Final 2007 WB 13 Monitoring Data-Year 2.doc December 8, PARSONS

Additional background information, including site history and details regarding previous investigations, is available in the Summary Report (Parsons and Geosyntec, 2008). As discussed in this Report, the purpose of the Pilot Study was to evaluate potential Solvay waste behavior during the anticipated SCA design phases (i.e., construction, operation, and closure). Therefore, the Pilot Study included cone penetrometer testing, geotechnical sampling, laboratory testing, instrument installation, test plot construction, and monitoring. The monitoring of extensometers, 30-ft grid, and settlement profilers was completed during the first year of monitoring, and the corresponding data were provided in the Summary Report (Parsons and Geosyntec, 2008), which also contains detailed descriptions of the pre-construction, construction, and monitoring activities associated with the Pilot Study. 1.3 REPORT ORGANIZATION Following this introductory section, Section 2 summarizes the data collected during the second year of monitoring (i.e., the piezometer, settlement plate, and inclinometer data). Section 3 contains references. In addition, Appendices A through C provide the field data.

6 WASTEBED 13 SETTLEMENT PILOT STUDY MONITORING DATA YEAR 2 SECTION 2 MONITORING 2.1 OVERVIEW This section summarizes the piezometer, settlement plate, and inclinometer data collected from November 2006 to November 2007 (i.e., the second year of Pilot Study monitoring). In addition, the monitoring schedule for next year is proposed. The Pilot Study location and instrumentation layout are provided in Figures 2.1 and 2.2, respectively. 2.2 PIEZOMETERS The piezometers were measured at least every other month from November 2006 through October 2007, as proposed in the Summary Report (Parsons and Geosyntec, 2008). Additional measurements (i.e., weekly measurements) were taken in December 2006 to coincide with monitoring of the Phase II PDI piezometers. The measurements from those piezometers are provided as a separate submittal on a quarterly basis. For the remainder of the monitoring period (i.e., January 2007 through October 2007), the Pilot Study piezometers were measured approximately once a month. The Pilot Study piezometer data are provided in Appendix A. Figures 2.3 through 2.7 show the changes in water level with time for the different piezometer depths (with respect to baseline water levels). Precipitation data are also included on these figures. The precipitation data were obtained from for zip code (Syracuse Hancock International Airport). For informational purposes, Appendix A and the figures include all data collected from September 2005 (i.e., the beginning of the Pilot Study) through October As indicated in the Summary Report (Parsons and Geosyntec, 2008), in 2004, O Brien and Gere installed three standpipe piezometers (i.e., BA-1S, PZ-01A, and PZ-01B) in Wastebed 13. The approximate depths for BA-1S, PZ-01A, and PZ-01B are 20 ft, 47 ft, and 61.5 ft below the top of casing, respectively. Because of the proximity of these piezometers to the test plot, they have been monitored at the same frequency as the Pilot Study piezometers to obtain background water level data. These data are also provided in Appendix A. 2.3 SETTLEMENT PLATES The settlement plates were measured at least every other month from November 2006 through November 2007, as proposed in the Summary Report (Parsons and Geosyntec, 2008). In November 2006, the settlement plates were surveyed twice. From December 6, 2006 through November 6, 2007, the settlement plates were surveyed every other month. A licensed surveyor also performed settlement plate measurements on December 6, 2006 to confirm the readings (see Appendix B). The settlement plate data are summarized in Table 2.1 and Figure 2.8.

7 WASTEBED 13 SETTLEMENT PILOT STUDY MONITORING DATA YEAR 2 informational purposes, all data collected from September 2005 (i.e., the beginning of the Pilot Study) through November 2007 are included in Table 2.1 and Figure INCLINOMETERS The inclinometers were monitored every six months during the monitoring period (i.e., November 2006 through October 2007), as proposed in the Summary Report (Parsons and Geosyntec, 2008). Plots of cumulative and incremental displacement with time for each of the inclinometers are provided in Appendix C. These figures are based on baseline measurements that were taken prior to construction of the test fill. For informational purposes, the last readings taken during the 1-year monitoring period (i.e., the readings from October 18, 2006) are included on the plots. 2.5 FUTURE MONITORING The second year of monitoring was completed at the end of October/beginning of November Because the Pilot Study is still providing useful information, the following additional monitoring activities are proposed between November 2007 and October 2008: piezometer measurements every three months; and settlement plate measurements every three months.

Data from October 17, 2005 appear to be anomalous because, upon review, it was observed that the data from that time period are inconsistent with field observations and baseline and subsequent readings performed by a licensed surveyor (i.e., a licensed surveyor performed the October 7, 2005 and October 25, 2005 readings). Therefore, these data are not included in this table or Figure Although some readings for SP-14, SP-15, and SP-19 are positive (i.e., they indicate upward movement), readings performed by a licensed surveyor on August 31, 2006 are not positive. As shown in Appendix B, all other settlement plate readings agreed relatively well with the licensed surveyor's readings.
