The Issue
The Issue
PIPA
The PIPA Committee Challenge
Federal law limits the authority of cities to
regulate pipelines
– How do you protect the public and the
environment?
– Provide developer flexibility?
– Provide for the needs of transmission pipelines?
– What can a City actually do within it’s authority?
Options
Setbacks vs. planning “zones”
Setbacks considered, but no consensus
within PIPA
Committee settled on planning zones as
recommended best practice
What is a Planning Zone?
Planning Area
An area surrounding a transmission pipeline …
based on characteristics of the pipeline and the
area surrounding the pipeline. … to protect
communities where new development is planned
near transmission pipelines.
A planning area can provide for the application of
additional development regulations, standards, or
guidelines to ensure safety when development
occurs in close proximity to a transmission
pipeline.
What is a Planning Zone?
Consultation Zone
An area extending from each side of a
transmission pipeline, … to describe when a
property developer/owner, … should initiate a
dialogue with a transmission pipeline operator.
How Big?
• Varies depending on the pipeline
and the land under consideration
• Suggested default is 660’ for gas
and 660 - 1,000’ for hazardous
liquids
Planning Zone
PIPA Planning Zone Components
• Information - Proposed use, pipeline
characteristics, land characteristics, recorded
easements
• Coordination – Between local gov’t., developer,
pipeline operator
• Conditional land use – Limit certain higher risk
land uses, encourage low risk uses, e.g. parking
lots, trails, WQ ponds etc.
• Design – Site layout, structural features,
structure orientation, emergency access, etc.
• Record – Easements, restrictions
One City’s Approach
Austin’s Ordinance
• Hazardous liquids lines >/= 8” diameter
• Focus on public safety, not protecting structures
– Difficult to evacuate populations (hospitals,
schools, daycare, etc) prohibited within 500’
– No ROW allowed in residential lot < 1 acre
– Buildings within 200’ of ROW must:
 Provide 1-hour evacuation time; and
 Early leak detection system (if commercially
available)
