Title: Sewer Use and FOG Ordinance


1
Sewer Use and FOG Ordinance
  • Chapter 28, Article IV, Sections 1-10
  • Presented by Department of Public Utilities

2
FOG Fats, Oils, and Grease
  • It is the byproduct of food preparation and
    cooking.
  • Comes from many food sources meats, nuts,
    plant/vegetable oils, dairy products, soups,
    gravies, condiments, sauces, pastas, poultry,
    etc.
  • It is insoluble in water, and can stick and
    accumulate in sewer pipes and equipment.

3
The Problem With FOG
  • As FOG cools, it sticks to the sides of pipes.
  • Eventually, it builds up and creates a blockage.
  • This leads to

4
  • Sanitary Sewer Overflows (SSOs)

5
  • One-third of SSOs and sanitary sewer blockages
    are caused by FOG.
  • FOG is a contributing factor in another
    one-third.
  • FOG is the 1 cause of dry weather blockages and
    sanitary sewer overflows.

6
The Cost of FOG
  • Last year, the City of Virginia Beach spent over
    1.4M on FOG abatement and SSO Cleanup.
  • It is estimated to cost 1,500 for City crews to
    respond to a single SSO.
  • DEQ may fine localities 32,500 per SSO
    occurrence, 1.6 million in a good year
  • Penalties are waived as long as we are
    implementing the mandates of the Consent Order in
    good faith

7
DPU FOG Control Efforts
  • DPU cleans up to 1,000,000 feet of sewer lines
    per year (10 FTEs equipment) - gt 1 M/year
  • 60-70 is Hot Spot cleaning same locations
    cleaned over and over (and over) again
  • Town Center, Lynnhaven Mall, Hilltop, Oceanfront,
    many small shopping centers, individual
    locations, multifamily housing

8
Example - Town Center
Public Utilities is cleaning sewer pipes in Town
Center about every two weeks
9
Laskin Road East of Hilltop

10
Residential Area - Centerville
11
FOG Control Pilot Studies at Two Shopping Centers
  • Typical strip malls anchored by a grocery store
    w/satellite restaurants
  • Nearly 100 of Grease Control Devices (GCDs)
    were either not functioning or not being cleaned
    often enough (or not at all)
  • Many owners did not know they had GCDs or
    thought that their restaurant did not generate
    grease
  • Many claimed GCDs were maintained

Purpose of a Sewer Use Ordinance and FOG Control
Program
  • Reduce SSOs
  • Reduce operation and maintenance costs
  • Maximize existing sanitary sewer system capacity
  • Enforce existing plumbing code
  • Comply with VDEQ Consent Order
  • A Credible FOG Reduction Program is a necessary
    requirement of a CMOM program which is mandated
    by the Consent Order

16
Sewer Use Ordinance - FOG
  • VA Beach developed a FOG Ordinance
  • It has evolved into a template for a Model
    Regional FOG Ordinance
  • Will impact Food Service Establishments (FSEs)
    Restaurants, food courts, school cafeterias,
    hospitals, grocery stores, prisons, food
    processors, day cares, social halls, others
  • Will impact FOG haulers and transporters

17
Sewer Use Ordinance - General
  • Prohibit industrial discharges as defined by HRSD
    regulations
  • Prohibit discharge of wastewater to stormwater
    system or surface water
  • Prohibit damaging or tampering with sanitary
    sewer system
  • Provide right of entry and inspection for
    purposes of enforcing the ordinance
  • Penalties (would be cumulative)
  • Class 3 Misdemeanor
  • Liable for cost and expense of damage/cleanup
  • 500 fine (per day, per occurrence)
  • DPU may bring legal action to enjoin misconduct
  • DPU could discontinue water service for
    non-compliance

18
How will this affect FSEs
  • Require registering GCDs with DPU similar to
    backflow device registration
  • Require installation or repair of GCD if
    necessary
  • Require regular maintenance of GCD
  • Require record keeping of maintenance
  • Require training and certification to service GCD
    provided by HRPDC
  • Annual inspection fee to recover program cost
  • Not imposed initially. Would be at actual cost
    (100-150/year)

Proposed Schedule
  • Management, Operation and Maintenance (MOM)
    program due to DEQ on December 31, 2008
  • FOG Reduction Program is key component of MOM
    program
  • DEQ/EPA will likely make approval conditional
    upon ultimate adoption of a FOG Control Ordinance
  • Localities to adopt MOA with HRSD in January, FOG
    ordinances in spring
