Subtask 1: NOA Samolina 1. Provide an Environmental Specialist under the direct supervision of a Certified Industrial Hygienist (CIH) and Professional Engineer (PE) to collect soil samples during the geotechnical evaluation of the site performed by the Geotechnical Consultant. The Geotechnical Consultant has proposed to drill two exploratory borings at the site using track -mounted hollow -stem auger drilling equipment. The borings will extend to depths of approximately 15 to 30 feet, depending on the depth and consistency of the bedrock encountered. SCA will collect up to 8 samples in each boring at various depths to determine naturally occurring asbestos (NOA) contents. SCAhas assumed 2 days of up to 10 hours in duration for such activities perthe schedule provided bythe Geotechnical Consultant. 2. While onsite, SCA will collect up to 6 additional surface soil samples in the proposed construction area for analysis of NOA contents. Depths of samples will be at approximately 1- 2 feet below ground surface, assuming that the top 2 feet of soils will be disturbed prior to re- grading of the site. Locations will be based on visual observations of site conditions. 3. Submit all samples to a contract laboratory for analysis by California Air Resources Board (CARB) 435. 4. Prepare a technical memorandum summarizing the results that will be submitted within 3 weeks of completion of the sampling event. The memorandum will present the sampling results and be reviewed by a CIH and Professional Engineer (Civil). Subtask 2: Preparation of an Asbestos Dust Mitieation Plan (ADMP) SCA will provide the expertise of a Professional Engineer, Certified Industrial Hygienist and Certified Asbestos Consultant to prepare an Asbestos Dust Mitigation Plan (ADMP) to comply with CARB's ATCM for Construction, Grading, Quarrying and Surface Mining Operations. The plan will discuss the following dust emissions sources, as required by Bay Area Air Quality Management District (BAAQMD). • Track -out onto the paved public road; • Active storage piles; • Inactive disturbed surface areas and storage piles; • Traffic on unpaved on-site roads; • Earthmoving activities; • Off-site transport of materials; and • Post -project stabilization of disturbed soil surfaces. In addition, the ADMP will include an Asbestos Air Monitoring Plan with recommended action and stop work levels for asbestos per the requirements of the ADMP (to be approved by BAAQMD). The document will be prepared and reviewed by a licensed Professional Engineer and Certified Asbestos Consultant (CAC). This scope of services assumes one round of review by IEC or City will be required prior to submittal of these documents to the BAAQMD. SCAalso has included costs herein to complete one round of revisions to address any BAAQMD comments. Additional revisions that may be required will be completed for an additional fee. Note that SCA will rely on IEC for preparation of any excavation plans and construction documents, if requested by the BAAQMD. The draft Plan will be submitted to IEC/City for review. Pending receipt of comments, SCA will provide a final Plan within one week of receipt of comments. The report will be submitted to the BAAQMD on behalf of the City of Redwood City , at the direction IEC, in PDF format in conjunction with the: • Application fee (estimated at $540 [current rate is $491 with annual 10% increase anticipated on 7/1/17] and Page 13 of 23 REV: 08-16-17 PR ATTY/AGR.Amendment No. 1/Infrastructure Engineering Corporation - CA Tank
