NGA Report: State Practices to Protect Drinking Water While Developing Shale ...Marcellus Drilling News
The National Governors Association (NGA) issued a 16-page report in July encouraging governors and their states to adopt policies that encourage a) the use of less drinking water for fracking, and b) the use of more recycling of flowback water in fracking. The report, titled "State Practices to Protect Drinking Water While Developing Shale Energy" (full copy below), is the result of a a 35-member panel that met in March.
Nov. 7, 2018- The Tennessee Department of Environment and Conservation (TDEC) is currently in the process of developing a Total Maximum Daily Load (TMDL) for the Harpeth River.
A TMDL is a pollution reduction study and plan that puts a waterbody on the path to restoration. In the case of the Harpeth River, TDEC is engaging stakeholders to help develop limits for phosphorus pollution.

Presents seven case studies of the use of natural drainage systems in land development projects in the Houston region. Documents the benefits of the approach, which includes: reduced required detention volume, increased lot yield, lower drainage infrastructure costs, higher lot sale price due to trail and natural space amenity adjacent to more lots, and appeals to the market interest in natural or green communities.

2. NATIONAL RESEARCH COUNCIL
• National Academy of Sciences created in 1863
• Private, nonprofit, society of scholars
• Dedicated to further use of science and technology
for general welfare
• NRC organized in 1916
• NRC furthers knowledge and advises the federal
government
• Governed jointly by Institute of Medicine and NAS
• See www.national-academies.org
WHY WAS REPORT PREPARED?
[EPA Requested It]
• Clarify the mechanisms by which pollutants in stormwater
discharges affect ambient water quality criteria and define the
elements of a “protocol” to link pollutants in stormwater
discharges to ambient water quality criteria.
• Consider how useful monitoring is for both determining the
potential of a discharge to contribute to a water quality
standards violation and for determining the adequacy of
stormwater pollution prevention plans. What specific
parameters should be monitored and when and where? What
effluent limits and benchmarks are needed to ensure that the
discharge does not cause or contribute to a water quality
standards violation?
• Assess and evaluate the relationship between different levels
of stormwater pollution prevention plan implementation and
in-stream water quality, considering a broad suite of
stormwater control measures (SCMs).
2
3. WHY WAS REPORT PREPARED?
[EPA Requested It]
• Make recommendations for how to best stipulate provisions in
stormwater permits to ensure that discharges will not cause
or contribute to exceedances of water quality standards. This
should be done in the context of general permits. As a part of
this task, the committee will consider currently available
information on permit and program compliance.
• Assess the design of the stormwater permitting program
implemented under the Clean Water Act.

9. REPORT HIGHLIGHTS: Monitoring Stormwater
• MS4 runoff well characterized (see Pitt’s National Stormwater
Quality Database)
• Industrial monitoring should be risk-based and improved
• Use continuous, flow-weighted sampling rather than grab
sampling
• Obtain flow and rainfall data
• Use biological monitoring
• Obtain statistically valid number of samples
REPORT HIGHLIGHTS: Management Approaches
• BMPs renamed:
Stormwater Control Measures (SCMs)
• Summary of SCMs
– Impervious cover reductions
– Rainwater harvesting
– Swales
– Silt fences
– Bio-infiltration
9
10. REPORT HIGHLIGHTS: Management Approaches
• Use watershed-based permitting for all sources
(wastewater and stormwater)
• Issue integrated permits by watershed
• Create lead permittee in each watershed
(delegation)
• Use residual designation authority to bring more
urbanized areas into the permitting program
• Establish biological end points for management
• Improve monitoring for Phase I MS4s
• Add monitoring for Phase II MS4s
REPORT HIGHLIGHTS: Management Approaches
• Establish numeric municipal action levels
(MEP as a number)
• Regulate product sale and usage
• Use effluent limits (loads or concentrations)
• Impose imperviousness limits
• Impose turbidity limit for construction sites
• Issue guidance on identifying high-risk industrial
facilities
• Provide more resources and funding
• Expand use of TMDLs (non-impaired waters)
• Regulate flow
10
11. REPORT HIGHLIGHTS: Key Conclusion
“…in its current configuration, EPA’s approach seems
inadequate to overcome the unique challenges of
stormwater and therefore runs the risk of being only
partly effective in meeting its goals.”
