Williams Requirements for Landowner & Third Party Construction
Rev.10/11/2017
The following Williams specifications are minimum requirements to be followed when planning land use development on or near Williams right of way.
Each proposed development or activity requires a site specific evaluation by a qualified Williams representative.It should be understood that the Williams
review of the proposed activity may require more stringent protective measures than outlined below.
PIPELINE FACILITIES AND LEGISLATION
Williams'transmission operation includes high-pressure steel pipelines ranging in diameter from 2"to 48". Williams pipeline facilities include compressor
stations,meter stations,storage facilities,cathodic protection equipment,valve settings and other facilities located within the limits of its rights-of-way,
leased,and fee properties.
Williams is regulated by the Department of Transportation,Pipeline&Hazardous Material Safety Administration(PHMSA).The pipeline safety regulations
are set forth in Title 49,Code of Federal Regulations,Part 192"Transportation of Natural and Other Gas by Pipeline—Minimum Federal Standards."
Williams will require that all Federal,State,and local ordinances and applicable utility set backs are complied with to the full extent.
ENCROACHMENTS
It is Williams philosophy to minimize encroachments and excavation activity within the limits of our pipeline right of way.Encroaching parties will design
projects such that proposed improvements remain outside the pipeline right of way.Improvements that will encroach into the right of way will be designed
and constructed such that the safe operation and maintenance of the pipelines is not diminished.Many of Williams right of way agreements prohibit
encroachments.Williams will enforce applicable provisions in its right of way agreements where it believes the continued safe operation and maintenance
of the pipeline facilities could be threatened.
NOTIFICATION AND CONSTRUCTION SAFETY REQUIREMENTS
1. In order to prevent unnecessary delays,Williams encourages close communication with our representative throughout your entire project.A
Williams representative should participate in all pre-construction meetings.In addition,Williams can conduct a safety/informational presentation
to any interested parties,including contractors,local governmental maintenance crews,and developers.
2. "One Call"systems require 48 to 72 hours'notice prior to any excavation activities or equipment use on or in close proximity to Williams pipeline
facilities.Dial 811 to be connected to your State One Call system.No equipment use or excavation will occur in the vicinity of Williams facilities
until notification to"One Call"has been made.A Williams representative will be on site prior to and during any equipment use or excavation
activities.Any crossings made without a Williams representative on site will be excavated at the excavator's expense to provide Williams an
opportunity to inspect all affected pipeline facilities.
3. Excavations must be barricaded to protect Williams pipelines from exposure to vehicular traffic and to ensure public safety.Williams
representatives must be provided safe access to all open excavations.Excavations must be properly sloped or shored in accordance with
OSHA regulations.
PLAN DESIGN AND REVIEW REQUIREMENTS
1. Residential and/or commercial developments will be laid out such that the right of way is designated as"open"or"common"space.Maintaining
an open right of way reduces public exposure and minimizes disruptions during pipeline maintenance and construction.Lot divisions will be
established on either side of the right of way resulting in the actual right of way being"open"or"common"areas.
2. In most cases,Williams will require the submittal of two or more full size plan and profile drawings to the appropriate Williams office for prior
review and written approval by Williams.All drawings must show,in detail,all of Williams facilities and other features that will allow Williams to
determine the impact of the proposed construction or maintenance activity on its facilities.Encroachment plans will include a scope of work,
description,and a location map depicting the project site area.Sufficient geographical references such as legal property lines,roads,and
appropriate deed information for the properties involved will be provided.
3. In order to ensure that all proposed improvements are designed in accordance with Williams encroachment specifications,Williams requires a
minimum of thirty business days lead-time to review proposed encroachments.Encroachments involving road crossings will require additional
8
review time.Any proposed road which requires pipeline modifications or a dedicated right of way will require significant lead-time.
4. If there are any changes to approved plans,additional review by Williams and subsequent written authorization will be required.
5. In some cases,there is a significant delay between the review and approval of submitted plans and actual construction.In such cases,
proposed encroachment related activities will be subject to Williams requirements in effect at the time the work actually takes place.
WILLIAMS EASEMENT,PERMITS AND AGREEMENTS
1. A Williams Encroachment/Foreign Line Crossing Permit Form or a letter of no objection may be required for any proposed construction within
Williams right of way.This document prepared by Williams,will outline the responsibilities,conditions,and liabilities of each party.If required,
this document must be executed by the encroaching party and in Williams possession prior to any work being performed on the right of way.
2. Williams will determine if a recorded encroachment agreement will be required for any proposed construction within Williams right of way.This
agreement,prepared by Williams,will outline the responsibilities,conditions,and liabilities of each party.This agreement will be fully executed
and in Williams possession prior to any work being performed on the right of way.
3. Williams will determine if a reimbursement agreement will be required for any construction within Williams right of way.This agreement,
prepared by Williams,will outline the reimbursement procedure for necessary and appropriate preliminary engineering and actual field
inspection work.This fully executed agreement,including a check made payable to the applicable Williams pipeline company for the estimated
cost of Williams services,will be in Williams possession prior to any work being performed on the right of way.
GENERAL REQUIREMENTS
1. No above ground structures or appurtenances are to be located within the Williams right of way.The structures and appurtenances include,but
are not limited to:utility poles,towers,foundations,guy wires,structures supporting aerial lines,satellite dishes,manholes,catch basins,utility
pedestals,transformers,fire hydrants,utility sheds,decks,swimming pools with associated improvements,etc.
2. An authorized Williams representative must be on site prior to and during any surface-disturbing work or equipment crossings performed within

3. No cut or fill on the Williams right of way is permitted without Williams written approval.
4. Williams,at its discretion,may request evidence of comprehensive general liability insurance coverage(up to$5,000,000 coverage)and other
appropriate and usual insurance prior to any activity,maintenance,and/or construction on or near Williams right of way and facilities.In the
event of significant excavation under or over Williams pipelines,Williams will require that the applicable Williams pipeline company be named as
additional insured on the Certificate of Liability Insurance.The insurance limits,terms,and conditions that may be required will be dependent on
the specific facilities potentially impacted and what would be usually and prudently obtained in similar industry situations.
5. All foreign lines will cross Williams right of way at an angle as near to 90 degrees as possible.In situations where there are multiple parallel
Williams pipelines,the proposed foreign lines will either cross over or under all of Williams pipelines in the right of way.No horizontal or vertical
bends are permitted within Williams right of way.Parallel occupancy of Williams right of way will not be permitted.
6. All foreign lines crossing Williams pipeline or related facilities will be installed with a minimum of 24"of clearance between the existing Williams
facilities and the proposed foreign line.The foreign line will be installed at a uniform depth across the full width of the Williams right of way.
Williams may require that all foreign lines be installed under its existing pipelines and related facilities.
7. Williams facilities are electrically protected against corrosion.Each metallic foreign line that enters or crosses Williams right of way must have a
test lead installed.In addition,the utility contractor installing the metallic foreign line must excavate and expose one or more of Williams existing
pipelines to provide for the installation of test leads by Williams employees.All necessary measures(coatings,electrical bonds,etc.)will be
taken to ensure that the proposed pipe or utility is adequately protected from potential interference effects.Requests for cooperative testing will
be directed to Williams Division Office,"Attn.:Supervisor,Asset Integrity."
8. Williams may require that foreign lines be identified with permanent aboveground markers where the lines enter and exit the Williams right of
way.It is the line owner's responsibility to obtain any rights to install the markers,and to maintain the markers.A direct burial warning tape
should be placed 12"to 18"above the foreign line and extend across the entire width of Williams right of way.
9. Foreign lines crossing Williams facilities will be installed in accordance with all applicable codes and requirements governing such installations.
10. Stockpiling brush,trash,or other debris on the right of way is prohibited,as it may conceal pipeline markers and hinder pipeline inspections or
routine maintenance.

Pipelines and Informed Planning Alliance
The Pipeline & Hazardous Material Safety Administration (PHMSA) initiated the
Pipelines and Informed Planning Alliance (PIPA)to help communities make risk- MFirrlin,,nand'
informed decisions for land use planning and development adjacent to In rmed
Planning
transmission pipelines. Allian€e
One way to protect communities and reduce transmission pipeline risks is for developers to be aware of
transmission pipeline locations and risks when making decisions regarding development within 1,000 feet
of pipelines. It is important that his dialogue between developers and pipeline operators occurs early in the
planning process while changes can more easily be made.
PIPA has developed recommended practices for protecting communities, protecting transmission
pipelines, and communicating among stakeholders. You can access PIPA's recommended practices at
http://primis.phmsa.dot.gov/comm/pipa/landuseplanning.htm.

Remember, Call Before You Dig.
A new, federally-mandated national "Call Before You Dig" number, 811, was created to help
protect you from unintentionally hitting underground utility lines while working on digging
projects. If you plan to dig or do any type of excavation, be sure to dial 811 at least three business
days before you begin. Calling 811 before every digging job gets your underground utility lines
marked for free.
Know what's below.
Call before you dig.
One free, easy call gets your utility lines marked
AND helps protect you from injury and expense.
How 811 Works
One easy phone call to 811 starts the process to get your underground utility lines marked for
free. When you call 811 from anywhere in the country, your call will be routed to your local One
Call Center. Local One Call Center operators will ask you for the location of your digging job and
route your call to affected utility companies. Your utility companies will then send a professional
locator to your location to mark your lines within a few days. Once your underground lines have
been marked, you will know the approximate location of your utility lines and can dig safely.
