CONSULTANT SCOPE OF WORK
• Assist staff with testing (lime reduction, air pollution
control pilot, capacity testing)
• Perform HRA risk modeling to assess District approach
on draft BAAQMD rule 11-18
• Complete 10% predesign on all major project elements:
• Solids Storage/Blending Facilities
• Dewatering Facilities
• Air Pollution Control Equipment
• Ash Handling
• Structural Code Improvements for Solids Building and Incinerators
• Complete 30% predesign for:
• Solids Storage/Blending Facilities
• Dewatering Facilities
• Air Pollution Control Equipment

THERE ARE SEVERAL AIR QUALITY CONTROL
DRIVERS
• Reliable Compliance with SSI MACT/Existing 129
Sewage Sludge Incinerator Regulations:
Avoid Reportable Bypass Damper events
Hydrogen Chloride Emissions (reduce caustic
chemical costs)
• Compliance with new BAAQMD Draft Regulation
11 , Rule 18
• Future air requirements compliance (e.g. PM2.5)
BAAQMD ISSUED DRAFT
REGULATION 11 , RULE 18 - OCTOBER 2016
"Reduction of Risk from Air Toxic Emissions
at Existing Facilities"
BAAQMD communicates
determine risk action levels required action plan
• Is Cancer risk>10/Million? Path to compliance(3 years or less)
• Address sources of risk
MEN • TBARCT for individual sources with
a risk>1/Million

PROACTIVE APPROACH TO COMPLIANCE
• Attended BAAQMD Workshop in
November 2016
Help District engage BAAQMD
during rule development: will
provide comments by December
2016
■ Leverage B&V experience with
- HRAs:
illyr • ->Intelligence gathering to
identify sources of risk
dL { • ->Engineering solutions for
Community Air Risk Evaluation reducing risk
(CARE)designated areas Rely on B&V combustion
sources experience
• District may be included in the
Phase 1 with early
implementation by 2021

RECOMMENDED BOARD ACTIONS
• Approve the Solids Handling Facilities
Improvements Project (Project),
• Authorize the General Manager to transfer up to
$2,000,000 in the Capital Improvement Budget from
existing solids projects being consolidated to fund
the Project, and
• Authorize the General Manager to execute a
Professional Engineering Services Agreement with
Black & Veatch Corporation in an amount up to
$2,000,000 for predesign work under the Project.
