This proposal includes services to continue ongoing semi- annual and annual compliance monitoring and reporting and continue remedial action sampling modified in accordance with the 2008 Response Action Plan Modification — 2011 Addendum (RAPMOD), dated August 1, 2011, and approved by the Florida Department of Environmental Protection (FDEP) on December 7, 2011. This proposal provides scope of services, estimated fee, and schedule to perform the semi-annual compliance and RAPMOD sampling and associated reporting. SCOPE OF SERVICES In accordance with the closure permit for Baker Landfill (Permit No. 0075982-004-SF), as modified April 19, 2010, and the RAPMOD noted above, semi-annual reports for compliance and remedial action sampling are due by May 1 and November 1 of each year. To meet this schedule and the reporting schedule associated with laboratory reporting established in Chapter 62-780, Florida Administrative Code (FAC), semi-annual sampling will be performed in February and August of 2015. Trinity will provide qualified, local field scientists and technicians for collection of samples. Gulf Coast Analytical Laboratories (GCAL) located in Baton Rouge, Louisiana will perform laboratory analyses and reporting. Details of the scope of services are summarized in the following tasks. 877 County Hwy. 393 North, Santa Rosa Beach, FL 32459 PHONE: 850.267.0759 ° FAX: 866.557.0076 www.preble-rish.com RR PREBLE-RISH INC CONSULTING ENGINEERS & SURVEYORS Tasks 1 and 2 - February and August 2015 Sampling and Reporting The following describes the proposed semi-annual sampling events for 2015 which will include field sampling activities, water quality analyses, and reporting of findings. Task 1 will be for the February event and Task 2 will be for the August event. The following will be performed for each event. Water Quality Sampling Water quality sampling will include the collection of groundwater samples, and, when enough water is available, surface water and seep samples. Sample collection will be performed for compliance and RAPMOD requirements. Field work, sampling methodologies, data evaluation, and data Quality Assurance/Quality Control (QA/QC) will be performed in accordance with Chapter 62-160, FAC, Standard Operating Procedures (DEP-SOP-001/01) (SOPs) and the closure permit no. 0075982-004-SF. Trinity will perform compliance sampling to meet the requirements listed in Sections H and K of the closure permit and the remedial action sampling requirements listed in Table 2 of the RAPMOD during each semi-annual sampling event. Semi-annual sampling will be performed during February and August, with the August event including annual sampling of the private Shue residential well. As required by Chapter 62-701.510(9) (a) FAC, Trinity will electronically notify the FDEP within 14 days prior to each scheduled sampling event. Trinity will also coordinate sampling internally and with the County, and also with GCAL to confirm sample bottles have been ordered and delivered on-schedule. Prior to the initiation of sample collection, field instruments will be calibrated according to factory instructions. Instrument calibrations will be documented on a field log and submitted to the County with the field sampling logs and laboratory analytical results as part of the formal reports. Water level measurements will be collected from each monitoring well across the site prior to sample collection. Static water levels in each required well will be obtained on the same day using an electronic water level indicator to the nearest 0.01 foot. During the collection of the static groundwater elevations, each monitoring well will be visually inspected. If any problems with the monitoring well are observed, Trinity will immediately notify the County of the problem. During purging procedures, indicator parameters will be measured and recorded in the FDEP water sampling logs in accordance with the current FDEP SOPs and closure permit requirements. For QA/QC purposes, Trinity will collect the appropriate number of equipment blanks and duplicate samples in accordance with the FDEP SOPs. 877 County Hwy. 393 North, Santa Rosa Beach, FL 32459 PHONE: 850.267.0759 ° FAX: 866.557.0076 www.preble-rish.com R PREBLE-RISH INC CONSULTING ENGINEERS & SURVEYORS Low-flow groundwater purging, and sample collection procedures will be followed in the field using a portable pneumatic bladder pump or similar device, where dedicated pumps are not present. For recovery wells, samples will be collected from the recovery pumps via sampling ports on the submersible pump drop-pipes. When recovery wells are not operating, samples will be collected from the annular monitoring wells. Sampling equipment will be decontaminated prior to all phases of purging and sample collection to reduce the potential for cross contamination between sample locations. During the purging and sampling operations, the groundwater will be monitored for pH, dissolved oxygen, specific conductance, temperature, turbidity, oxidation reduction potential (ORP), colors, odors, and sheens (by observation), and ferrous iron for those monitoring wells which have been selected for Monitoring Natural Attenuation (MNA) in accordance with the RAPMOD. Monitoring of these parameters will provide an indication of stabilization of the groundwater quality prior to sample collection. These parameters will be recorded on the sampling log. Once the indicator values are stabilized and a sufficient volume purged from the well, sample collection will begin. After sample collection, the samples will be prepared, preserved as necessary, and shipped to GCAL using industry standard chain-of-custody procedures. Laboratory Analysis, Review, Database Update Water quality analyses will be performed by GCAL in accordance with Chapter 62-160, FAC, DEP-SOP-001/01, and the closure permit. GCAL is certified by the Florida Department of Health Environmental Laboratory Certification Program (DoH ELCP). GCAL will perform analyses as listed within the Okaloosa County closure permit and RAPMOD in standard turn- around times (approximately two calendar weeks) and provide an electronic report and data package deliverable to Trinity. A Level II quality control data package will be included within the laboratory report for each sampling event. Upon receipt of the laboratory report and data package, Trinity will perform a quality assurance/quality control (QA/QC) review consisting of a detailed assessment of the equipment and trip blanks, as well as the field duplicates in addition to the laboratory provided case narratives and matrix spikes/matrix spike duplicates. Based on the review, Trinity will determine the validity and usability of the data. Reporting Trinity will review the analytical data, and prepare tables, figures, and a written report for each of the two semi-annual events conducted during 2015. The reports will include a section on results of compliance monitoring and results of remedial action monitoring. Trinity will also include a section in the reports addressing the operation and maintenance of the monitoring and 877 County Hwy. 393 North, Santa Rosa Beach, FL 32459 PHONE: 850.267.0759 * FAX: 866.557.0076 www.preble-rish.com rR PREBLE-RISH INC CONSULTING ENGINEERS & SURVEYORS remediation system at Baker. In accordance with the RAPMOD, reports will include a discussion of the effectiveness of monitored natural attenuation. Conclusions and recommendations will be provided in each report regarding monitoring location compliance and the effectiveness of the remediation system. These tasks do not include responses to requests for additional information (RAI) that may arise from the FDEP. RAI’s resulting from deficiencies in workmanship will be addressed by Trinity; however, RAI’s unelated to work scope deficiency will result in additional fees as necessary. These fees do not include any additional field activities such as installation of additional wells, additional sampling, or the further laboratory analysis of data. DELIVERABLES The report for each sampling event will be submitted to the County in draft format. The draft report will include a complete electronic copy of the report in pdf format with a separate copy of the text in .doc format for tracked-changes review revisions and comments by the County. Trinity will make appropriate revisions to the draft report based on County input and prepare the final version for submission to the FDEP by the May 1 and November 1 deadlines.
