Mercury Manometer

Investigation and Remediation:A COOPERATIVE EFFORT WITH

THE NATURAL GAS INDUSTRY

Bill Schramm

History of Meter Use

• 1920’s Development of natural gas collection and distribution systems

• Mercury meters (to present)

• Dry flow meters (from ’70s)

• Electronic (from 90’s)

Meter Applications

• Field development

• System development

• National distribution network

• Other industrial applications

• Domestic applications

• Meter servicing operations

Typical Mercury Meter

What are the typical

configurations?

Single Run

Multiple Run

Shed

Building with Multiple Meters on

a Manifold

Tower in Flood-Prone Locations

Platform inShallow-Water

Locations

Local Distribution

Compressor Stations

• Records review

• Field verification

• Initial Sampling

• Iterative excavation

• Confirmation Sampling

Confirmation Samples

• Final remedial report received• Confirm data QA/QC• Review data for compliance with

RECAP in LAC 33:I.Chapter 13• Management Options:

SSni=2.3ppm, MO1ni=23ppm, MO2&3=site specific levels

• Prepare NFA-BOD for site/sites meeting requirements

• Site/sites receive closure with approved NFA-ATT

Site Closure

• 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.

How Many?

How 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
