Title: Mercury Manometer Investigation and Remediation: A COOPERATIVE EFFORT WITH THE NATURAL GAS INDUSTRY Bill Schramm
1Mercury Manometer Investigation and
RemediationA COOPERATIVE EFFORT WITH THE
NATURAL GAS INDUSTRYBill Schramm
2History of Meter Use
- 1920s Development of natural gas collection and
distribution systems - Mercury meters (to present)
- Dry flow meters (from 70s)
- Electronic (from 90s)
3Meter Applications
- Field development
- System development
- National distribution network
- Other industrial applications
- Domestic applications
- Meter servicing operations
4Typical Mercury Meter
5What are the typical configurations?
6Single Run
7Multiple Run
8Shed
9Building with Multiple Meters on a Manifold
10Tower in Flood-Prone Locations
11Platform in Shallow-Water Locations
12Local Distribution
13Compressor Stations
14Investigation and Remediation Plan
- Records review
- Field verification
- Initial Sampling
- Iterative excavation
- Confirmation Sampling
15Remediation Activities
16Meter Dig
17Shed Dig
18Run Dig
19Livestock Pasture Dig
20Iterative Dig Sample
21Iterative Dig Sample
22Iterative Dig Sample
23Confirmation Samples
24Site Closure
- Final remedial report received
- Confirm data QA/QC
- Review data for compliance with RECAP in LAC
33I.Chapter 13 - Management Options SSni2.3ppm, MO1ni23ppm,
MO23site specific levels - Prepare NFA-BOD for site/sites meeting
requirements - Site/sites receive closure with approved NFA-ATT
25How Many?
- There are an estimated 25,000-30,000 locations
throughout Louisiana. - Since 1991 over 4900 have been investigated with
DEQ oversight. - Of the 4900, 2100 have been cleaned up with DEQ
oversight, the remaining 2800 did not require
corrective action. - Currently there are approximately 400 to 500
sites in process with LDEQ.
26How does DEQ want to move forward?
- Establish a cooperative policy to get
responsible parties to voluntarily report and
manage their sites - Develop citizen outreach to inform and protect
- Establish database/GIS information to aid in
integrating mercury distribution to water quality
issues and source control
