CITY OF REDLANDS CH2M HILL, CALIFORNIA, INC. By:` k.-.,-i�C� y By: Patricia Gilbreath Jag Salgao Mayor Vice President, CIyi2M HILL, Inc. ATTEST: By: (. Lore Poyzer City Clerk 2 Task Order 19 Redlands Water Resources Management Plan 2001 Update to the Sanitary Survey for Mill Creek Watershed Attachment A Draft Scope of Work Purpose The purpose of this task order is to produce an updated Sanitary Survey for the Mill Creek watershed in compliance with all applicable regulations. Preparation of Sanitary Surveys is required by Section 64665 of the California Code of Regulations, Title 22. The code requires that the surveys be completed at least every five years. The last filing of the Sanitary Survey of the Mill Creek Watershed was in 1996. The next filing of a Sanitary Survey of this watershed should be performed in 2001. The goal of this project is to update the Sanitary Survey and submit to the California Department of Health Services (DHS). Scope The update to the Sanitary Survey of the Mill Creek Watershed will generally follow guidance developed by DHS and American Water Works Association (AWWA), which was also used in the preparation of the previous Sanitary Survey. The structure of the Sanitary Survey document as recommended by AWWA guidance document is: • Summary • Section 1. Introduction • Section 2. Watershed and Water Supply System • Section 3. Potential Contaminant Sources in the Watershed • Section 4. Watershed Control and Management Practices • Section 5. Water Quality • Section 6. Conclusions and Recommendations • Attachments: Completed Watershed Survey Forms, water quality data summaries, etc. Through the execution of this scope, these chapters will be updated with new data and new analysis. The chapters will be updated in three main phases: data collection, data analysis, and report update. CH2M Hill proposes to complete this update through the following tasks. TO19SCOPEMI LLCREEK.DOC 02/26/01 1 Task 1— Kick -Off Meeting and Ongoing Milestone Meetings An initial kick-off meeting will be held to confirm the project objectives and to discuss the project schedule and anticipated issues. Subsequently, meetings will be held to discuss project progress and specific technical issues as they arise. We currently anticipate three meetings to address each of the following topics: • Project Kick -Off meeting: Confirm project objectives and discuss component items to be covered during the update to the Sanitary Survey • 50 Percent Milestone: review project progress and review/identify Potential Contaminant Sources • Review of Final Draft Report Meeting attendees are expected to be City of Redlands staff and CH2M HILL. However, additional parties (e.g., agencies) may be included as warranted. Task 2 - Update of Section 2 Watershed and Water Supply System Local and state agencies and other sources of data will be contacted to obtain new data for these updates: 2.1 Land Use and Natural Setting. The AWWA Guidance Manual recommends that the Sanitary Survey include a physical and hydrologic description of the watershed. CH2M Hill will update the following: Land Use. To update existing land uses we will rely on City and County landuse data and/or General Plans. Land use designations will be identified on a map. Land Ownership. Land ownership is critical to the Sanitary Survey as it reflects jurisdiction ' over existing activities and portends the potential implementation of future watershed management measures. Ownership for large tracts will be identified, such as National Forest, open space, and ranch holdings. Natural Setting. It is expected that only minor changes will be needed for this section. We expect that most of the changes will come from the biological aspects of the watershed's natural setting such as vegetation and wildlife. 2.2. Existing Hydrology. We expect minimal changes to this section that will be based on review of updated USGS and NOAA data that is available on the Internet. Also, changes that stem from SCE re -licensing or changes in diversion points will be updated. 2.3 Water Supply System. The history of the water supply system, the existing water supply system, the water supply sources, and the management of those sources will be updated per new information obtained from the recently completed Urban Water Management Plan, the Water Systems Facilities Master Plan, other pertinent documents, and discussions with City staff. Task 3 - Update of Section 3 Potential Contaminant Sources in the Watershed The Mill Creek watershed is mostly National Forest. We anticipate that there will be few problems associated with human activities in these areas. TO19SCOPEMILLCREEK.DOC 02/26/01 2 3.1 Conduct Survey to verify/identify Potential Contaminant Sources. Using the updated information collected in Task 2, we will characterize land uses that potentially affect drinking water quality in the watershed. If needed, additional data will be gathered from City, County, state and federal agencies. As part of this task, we expect to contact the following agencies and organizations: • Caltrans • Forest Home Christian Conference Center • San Bernardino County Department of Environmental Health Services • Regional Water Quality Control Board • California Department of Health Services • United States Forest Service After completion of a desk -top survey, a one day drive -by "windshield survey" and on -foot inspections of high priority areas of the watershed will be conducted. The field survey will be targeted at investigating specific areas within the watershed anticipated to contain the most problematic contaminant sources. The methodology used to compile and describe information regarding potential contaminant sources will be presented in the Sanitary Survey. 3.2 Potential Contaminant Sources. The AWWA Guidelines identify several potential contaminant sources that should be considered in the Sanitary Survey. Categories of contaminants could include microbial sources, nutrients, sediment, organics, and heavy metals. Information on existing Potential Contaminant Sources (PCS) identified in the current Sanitary Survey willbe updated and new sources will be added per information gathered in task 3.1. 3.3 Anticipated Growth and Projected Changes. CH2M HILL will identify specific details regarding anticipated growth and projected changes in sources of contaminants by reviewing local and County General Plans and through discussions with local planning departments. Deliverable: Upon completion of Task 3, CH2M HILL will develop the 50 percent draft version of the Sanitary Survey document, AWWA Guidance Checklist, summarizing all activities and findings to date. A meeting with City of Redlands staff will be held to review the draft findings; concentrating on the contaminant sources identified to ensure that they will be portrayed accurately in the Sanitary Survey. Task 4 — Update of Section 4 Watershed Control and Management Practices A variety of treatment and non -treatment solutions are available for controlling pollutants in the watershed. Practices listed in the current Sanitary Survey will be reviewed and updated to reflect new information and technologies as provided by the City of Redlands. Task 5 — Update of Section 5 Water Quality 5.1 Drinking Water Regulations and Surface Water Treatment Rules (SWTR). CH2M HILL will update the requirements for all drinking water regulations including the Interim Enhanced Surface Water Treatment Rule. TO19SCOP EM I LLC R E E K. DOC 02/26/01 3 5.2 Constituents of Concern. CH2M HILL will conduct a detailed analysis of existing water quality data to verify that no exceedance of the SWTR contaminants of concern have occurred since the last Sanitary Survey was prepared. Available water quality data will be reviewed and evaluated to determine the City of Redlands' ability to meet the requirements of the SWTR. The constituents of concern to be reviewed include: • Giardia lamblia • Cryptosporidium • Enteric viruses • Coliform (including fecal coliform and Escheria coli) • Trihalomethanes, haloacetic acid, their precursors, and other disinfection byproducts • Turbidity Additional constituents that may be evaluated, if appropriate, are grouped by AWWA as follows: nutrients; total dissolved solids, chloride, and bromide; hardness; metals; organics; and, radiological constituents. 5.3 Evaluation of Monitoring Data. The evaluation of this data will require linking known constituents of concern to potential sources, when and where possible. In addition, we will identify temporal and geographic water quality trends, compare raw and finished water quality to drinking water standards, and project changes in water quality. Task 6 — Update of Section 6 Conclusions and Recommendations 6.1 Conclusions. CH2M HILL will provide a summary of the major findings from the updated information including a description of identified potential contaminants, water quality issues and existing management measures. 6.2 Recommendations. CH2M HILL will summarize progress on the recommendations listed in the existing Sanitary Survey. CH2M Hill will discuss with City staff any new recommendations that could be made based on the updated information gathered in this Sanitary Survey. Any new recommendations will be discussed in this section. Task 7 - Prepare Draft and Final Report The Sanitary Survey will be prepared in three phases: 50 percent submittal, Final Draft and Final. The Final Draft Sanitary Survey will include an Executive Summary and Introduction to the document, final graphics, incorporated comments from City of Redlands, and conclusions regarding the potential for contamination and any recommended control methods. CH2M Hill will submit the Final Draft Sanitary Survey to the City of Redlands and DHS. We would also recommend that DHS staff be invited to comment on the 50 submittal to see in advance that their concerns have been incorporated. Upon receipt of comments on the Final Draft, we will make appropriate revisions and prepare the Final Sanitary Survey for submittal to DHS. CH2M Hill will deliver to the City five bound copies of each of the report submittals.
