(ENGINEER) for study and report professional services. 1. The Basic Services of ENGINEER as described in Section 1 of said Agree- , ment are amended and supplemented as follows: The Scope of Services to be provided under this contract will include: Procure services of drilling and laboratory subcontractors. i ;. Prepare a brief site sampling plan and health and safety plan, which will specify the sampling and sample handling procedures. Submit to the Cityfor review prior to conducting sampling. Conduct sampling of the site as described in letter to City of Redding from CDM dated May 21, 1990 regarding revised approach (Attachment 1 ) . A total of 54 soil samples will be collected, from the surface and from various depths in drilled boreholes. Samples will be analyzed for the i ' compounds listed in the Scope of Work presented in CDM's original proposal to the Owner (Attachment 2 ) . Samples will be collected in pre-cleaned 8- ounce glass jars with Teflon-lined lids provided by the laboratory, and placed in I coolers. Samples will be preserved with ice until hand-delivered to the laboratory. Sample analysis will be requested on a 2-week turnaround. Conduct the health risk assessment based on the results received from the laboratory. Exposure scenarios will consider long-term effects of soil ingestion for park and residential housing site uses. Contaminants of concern will be based on the results of the sample analyses. Both carcinogenic and non-carcinogenic effects will be considered. EPA and any available State of California guidance will be 1, followed. The result of the risk assessment will be a number expressing the excess risk of contracting cancer or j, non-carcinogenic diseases based on ingesting a given amount of site soil. The site risks will be compared to risks calculated for background soil samples. The assessment will Page 1 of 3 • I '' assume a no-action condition, that is, that those risks would be present if the City did not change or remediate the site in any way. If the risks appear to be significant, Engineer will communicate this to Owner as soon as possible, to determine if the scope of the Risk Assessment should be increased to evaluate additional pathways or exposure scenarios. ▪ Prepare a Liability Assessment. The liability assessment H will look at the risks developed in the risk assessment, compare them to risk levels employed by other regulatory li agencies such as EPA, State of California, or other states and present the comparison to help the City make a risk management decision. A range of site remediation options such as what would be prepared for an EPA study will be developed. These options could include No Action, grading/soil management, cover options, or complete soil removal/offsite disposal. Order of magnitude costs will be presented for each alternative described. ▪ Prepare a Draft Report. The findings of the Risk and Liability Assessments (Tasks 1, 2, and 3) will be presented in a Draft Report to the Owner. The Engineer will make a presentation of the draft report findings to the City staff. If appropriate, recommendations for any further study will be made at that time. Engineer will finalize the draft Report at the direction of the Owner, incorporating any changes or comments as appropriate. The final report will be presented in a way to clearly communicate the results of the Risk Assessment to the City and the public. • Project management, meetings and QA/QC. Two meetings at the site are anticipated for the Engineer's Project Manager and Risk Assessment Task manager. Time has been included for review of the deliverable by CDM senior staff who have expertise in this area. Brief monthly reports will be submitted by Engineer to Owner discussing project status. General administration of the contract and invoice preparation has also been included in this task. 3. The time periods for the performance of ENGINEER's services as set forth in Section 4 of said Agreement are amended and supplemented as follows: A draft report will be submitted to the OWNER within 120 calendar days of execution of this Agreement. A final report will be submitted promptly thereafter as soon as any changes or modifications are agreed upon. 4. The method of payment for services rendered by ENGINEER shall be as set forth in the Billing Rate Schedule (Attachment 3) . ENGINEER estimates that project costs shall not exceed $60,587, based on the labor and expenses estimate included in Attachment 3 required to complete the Scope of Basic Services. Any changes to the scope of work described in Page 2 of 3 4IP 111 Exhibit A, Paragraph 1, agreed to by ENGINEER and OWNER, will be reflected by a change in the Not To Exceed total, incorporated as a change order to this contract. 5.

Eight (8) background samples will be collected from outside the site, in an area to be identified at the kick-off meeting, using the drill rig. The background samples will be collected from 2 borings, at the surface, and depths of 2 feet, 5 feet, and 10 feet, to provide a background comparison for all horizons. Approximately 10 percent of the samples will be split in the field to create field duplicates, as a quality control check. This will bring the number of samples to 41 field samples, 8 background samples, and 5 duplicates, for a total of 54. Laboratory costs have been revised to reflect a quantity discount (based on costs provided by Eureka Laboratories of Sacramento). The new proposed project total would be $58,387, with the expanded sampling and drilling costs, and slight increases in the data analysis tasks. This total does not include CDM's time or materials to prepare graphics or presentation aids for a community meeting, although, as we discussed, we could prepare such material as requested.

PROJECT APPROACH CDM is proposing a phased project approach, based on the site conditions the and project budget. Phase I is g geared as an initial risk assessment to complement the City's currently approved budget for the project. Phase II consists of optional tasks to supplement the site investigation should the City request further study. Specific activities under both Phase I and Phase II are discussed below under each task. SCOPE OF WORK Task 1 - Site Testing j In order to characterize the Enterprise Ponds site to determine potential risk, samples of the soil will be required. The site consists of approximately 130 acres; laboratory analytical costs and the preliminary budget constraints will by necessity limit the amount of sampling that can be performed in Phase I. Soil testing data presented by J.H. Kleinfelder in their site assessment reports (April and July, 1987) will be utilized by CDM in Phase I. However, the Kleinfelder data covers only one of the abandoned pond areas (Pond No. 1, east of the Victor Avenue extension, and 10 acres in size) , which was slated for school construction. Additionally, this data does not provide information on many important contaminants, such as organics, which are integral to a complete risk assessment. In order to use analytical dollars in the most effective manner possible, CDM proposes a biased sampling approach, which will sample the locations most likely to .i. have any potential contamination. Those areas of the site not sampled by Kleinfelder will be ranked according to their potential for containing chemicals of concern; areas with high potential will be sampled in Phase I. It is anticipated that these areas will include the pond areas that accepted raw sewage, the aeration basin, the evaporation/percolation trenches, and the current rubble pile. The southern area of the site which is currently leased for cattle grazing is anticipated to be a low priority area for Phase I sampling. 2-1 • 411 In order to provide sufficient data for the Phase I risk assessment process, while at the same time stretching the analytical budget, the following list of analytes is proposed. The analytes have been selected because they are typically listed on EPA and State of California sewage sludge regulations; their selection is also based on their potential human toxicity. The list may be altered after further review of the background data for the Enterprise ponds: • Metals (CAM TTLC) . • Pesticides (EPA 614, 615) . .d. • Extractable Organics (PAHs) (EPA 610). 1 ' Dioxin (20% of the samples) (EPA 613). PCBs (20% of the samples) (EPA 608) . Analysis for volatile organics is a low priority in Phase I since it is likely that volatiles would have left the sludge during the time since site shutdown. Also, although there is a potential that plating chemicals may be present, cyanide analysis was not considered a high priority in Phase I since other metals such as chromium and copper which will be analyzed can be used as indicators of plating processes. Sampling for human pathogens such as viruses is an option for Phase II; it has not been included in Phase I, since it is unlikely that pathogens would still be viable given the time since system operation. Sampling methodology in Phase I will consist of obtaining surface samples from the upper 6 inches of soil from random locations at each selected area. Twenty (20) samples and two (2) field duplicates will be collected, for a total of 22 samples. Samples will be collected using a stainless steel trowel. Pre-cleaned 8-ounce glass jars with teflon-lined lids will be obtained from the laboratory. Sampling equipment will be thoroughly cleaned between each sample using a detergent wash and deionized water rinse. Laboratory analysis will be performed by a State-certified local Redding-area laboratory, if possible. Samples will be hand-delivered to 2-2 • the laboratory by CDM personnel. It is anticipated that analyses can be completed by the lab in a 2- to 3-week period. Probably the most important option to be considered by the City for Phase II would be monitoring of the groundwater underlying the site to determine if any site contaminants have entered the groundwater; this recommendation will be dependent on the results of Task 1. Other Phase II studies could include complete surface sampling of all areas within the 130-acre parcel; sampling of subsurface soils (from 2 to 3 feet below grade) at selected locations, to determine potential risks to workers involved in grading the site. Costs for these potential Phase II tasks have not been included in this proposal, but could be prepared at the City's request. Task 2 - Health Risk Assessment The objective of the Phase I Health Risk Assessment (HRA) is to evaluate potential health risks at the site. To accomplish the scope of this project with the budget available, the Phase I HRA will be a preliminary evaluation which will focus on risks associated with selected chemical groups, exposure pathways, and land uses. The purpose of the Phase I HRA is to provide the City of Redding with information necessary to evaluate various site development options and the future costs, data requirements, and potential liabilities that may be associated with those options. The Phase I HRA will use soil contamination data generated in Task 1 to evaluate potential health risks from using the land in its present condition under the proposed land use alternatives. The Phase I HRA will also identify any additional data which may be needed to more thoroughly evaluate potential health risks at the site. This phased approach to health-risk evaluation for this site is appropriate and cost effective, in view of the present uncertainty regarding the extent and nature of contamination at the site. The budget available for measurement of soil contaminants is adequate only for a screening-level analysis. This means that a relatively small number of soil samples (22) will be analyzed for the presence of selected target compounds. The health risk evaluation will be based on these compounds and 2-3 ,4111 the assumption that no site remediation (i.e. , removal of residual sludge) would occur. • The scope of the Phase I HRA will be limited to a consideration of potential health risks from exposure to soil at the site. Other possible exposure pathways, such as groundwater and air, could be included in Phase II. The emphasis of the HRA will be on health effects associated with long-term • exposure to soil contaminants. Both carcinogenic and noncarcinogenic health effects will be evaluated. Any subgroups of the population which may be especially susceptible to specific adverse health effects from specific target compounds will also be identified. I Risk assessment methods and assumptions for this HRA will �P generally follow most recent EPA guidance documents, especially as outlined in the Risk Assessment Guidance for Superfund, Volume I: Human Health Evaluation, Part A (1989) . CDM will consult with California Department of Health Services • regarding exposure assumptions and toxicity criteria to be used in the HRA. i.. Based on the results of the Phase I HRA, additional chemical data and health risk analysis may be recommended for Phase II for all or parts of the site. A discussion of health risk issues identified by the HRA will be provided, along with different technical approaches which could be used to provide a more thorough evaluation of potential health risks under various land use options. Task 3 - Liability Assessment Although the site is exempt from any waste site closure regulations, there is a slight potential that hazardous chemicals may be present that could present a risk to future residents or park users. Under this task, CDM will evaluate the results of Tasks 1 and 2, and develop several options for site management which would reduce the City's liability. At this stage, it is not possible to predict whether the risk is insignificant, or how complicated the various remedial options may need to be. CDM's goal will 2-4 • .• be to provide information to the City so that informed decisions can be made. Risk reduction options might include import of low permeability soils or an impermeable membrane as a cap over the pond areas; excavation and removal of contaminated soils and offsite disposal; or a system of grading which would place contaminated soil below the level where it could be contacted by future site uses. In particular, CDM will utilize its expertise in sewage sludge management to suggest ways to eliminate liability as a result of any residual sludges on site. Task 4 - Final Report/Site Action Plan A draft report will be prepared which will summarize the Phase I tasks performed, including the field sampling, laboratory analytical results, the results of the Phase I Health Risk Assessment, and the liability assessment. CDM will present recommendations for any further work to better define potential risks or site contaminants in Phase II. Recommendations will also be made to the City as to options for management of the site to reduce environmental liability. The draft report will be presented to the City for review and comment. Comments from the City will be incorporated into a Final Report for distribution. Task 5 - Project Management/Meetings with the City Activities under this task will include the initial kickoff meeting with the City and a site visit for the Project Manager and the Risk Assessment Task Manager. A final meeting with the City to present the results of the project has also been budgeted. Costs are also included in this task for ongoing communication between CDM and the City. Monthly reports to the City are an option which CDM can prepare at the City's request, but they are not included in this budget, given the relatively rapid project 1 schedule. Also included in this task are hours for technical review and i " quality control activities to assure that the deliverable provided to the City is technically sound and defensible. 2-5 AT 3 j'.
