City of Pleasanton—Villages at the Quarry Project 15183 Consistency Checklist Consistency Checklist 61 exposure durations. The project MEIR is identified as the sensitive receptor that is most impacted by the proposed project’s construction. In identifying the MEIR, the HRA also considered future potential residential receptors for a proposed project to the east that is also within the proposed project site’s 1,000-foot zone of influence. It conservatively assumed that these new residences at Arroyo Lago would be constructed and occupied prior to the proposed project’s construction, which represents the most conservative case. Summary of Project-related Health Risks at the Off-site Project MEIW Cancer risk and the chronic HI was calculated for the off-site Maximally Exposed Individual Worker (MEIW) based on the maximum DPM concentration at identified off-site receptors. 8-hour breathing rates for moderate intensity activities of 230 liters per kilogram for 8 hours (L/kg per 8 hours) (applicable to 16–70-year-old adults) were used to calculate the daily dose via the inhalation route to the worker. The analysis assumes a start age of 16 years and an exposure duration equivalent to the construction duration of 5.1 years. Since the construction emissions were modeled as a non-continuous source, the worker adjustment factor was used to adjust for the proper exposure concentration. When modeling a non-continuously emitting source (e.g., operating for 8 hours per day and 5 days per week), the modeled long-term average concentrations are based on 24 hours a day and 7 days per week for the period of the meteorological data set. Even though the emitting source is modeled using a non-continuous emissions schedule, the long-term concentration is still based on 24 hours a day and 7 days per week. Thus, this concentration includes the zero hours when the source was not operating. The worker adjustment factor (WAF) is used to determine the long-term concentration the worker is breathing during their work shift. Therefore, the long-term concentration is adjusted so it is based only on the hours when the worker is present. For this proposed project, assuming the emitting source and worker’s schedules are the same, the adjustment factor is 4.2 = (24 hours per day/8 hours per shift) x (7 days in a week/5 days in a work week). HARP2 provides for the specification of the WAF for worker cancer risk assessments, and this was entered as 4.2 to make this adjustment. Summary of Project-Related Health Risks to Students Student cancer risk and chronic hazards were determined for the Montessori School of Pleasanton (within 1,000 feet of the proposed project site).
