  • 3SpecificChallengestoIndustry:

    Current biosolids management not sustainable:

    20% projected population increase by 2030

    Limited landfill capacity

    Longer hauling distances

    Increasing costs (current range $45-$90 per wet ton)

    State and Federal Regulations:

    Increasing restrictions on current practices land application and ADC

    Local Restrictions:

    Solano County Ordinance

    San Joaquin AQMD Rule 4565 (Biosolids eliminated as ADC; incorporation within 3 hours currently 24 hours)
