Corporate Social Responsibility

Williams Integrated Management System

Management System Overview

The Williams Integrated Management System (WIMS) is the platform from which we provide policies, requirements, guidelines, procedures, standards, specifications and other documents that are used to design, build, operate and maintain our assets. It defines how we manage and reduce physical risk to our assets and people.

Our Commitment

We’re committed to continuous improvement and conducting business safely, efficiently and reliably to achieve the greatest benefit for all stakeholders. We meet or exceed all applicable laws and regulations and facilitate full and open discussion to address responsible standards and practices where laws and regulations do not exist.


Our expectation is that every employee and contractor adheres to WIMS and is dedicated to Operational Discipline – Doing The Right Thing, The Right Way, Every Time.


Goals Under this Commitment


  • Integrate stewardship into core business activities.
  • Make environmental, health, safety and physical risk management considerations a core component in existing operations and in the planning, design and construction of new and expanded facilities into our business and decision process.
  • Establish a system for total employee involvement in processes and a means to measure that participation.


  • Promote awareness among customers and in the communities where we operate.
  • Cooperate and coordinate, in the spirit of partnership, with local, State, and Federal authorities, as well as other stakeholders, on relevant matters and incidents.


  • Incorporate critical performance metrics into existing management reporting systems.
  • Include the achievement of high standards of excellence as a component of the performance review process for each employee.
  • Perform process assessments and independent compliance audits at a frequency appropriate to the size and nature of the operations and facilities, and implement corrective action.
  • Perform evaluations of incidents and near misses through formal investigation including the identification of basic and root causes and steps to prevent reoccurrence of a similar event.
  • Assess risks of existing operations, new business ventures and acquisitions.


Managerial Responsibility for Health and Safety Issues

The leadership of each Operating Area is responsible for implementing management systems with appropriate Operating Requirements, Operating Guidelines, Site-Specific Procedures, and other standards to comply with Company expectations and compliance. WIMS incorporates compliance regulations, industry codes and standards, industry best practices and experience into WIMS documents.


The Williams Commitment to the WIMS procedure establishes the minimum responsibilities to accomplish successful implementation of WIMS through active and visible commitment by senior leadership, delegating responsibilities and measuring Environmental, Health & Safety (EH&S) participation and performance by all employees. It sets for the requirement of the full support, understanding and engagement of WIMS standards and procedures by all employees. Compliance with all applicable WIMS requirements is achieved through the demonstrated completion of all training and the use of all appropriate forms or procedural documentation.

Operating Requirements

Operating Requirements must be followed to comply with regulatory requirements and Williams expectations unless an approved variance is in place.

Project Standards

Project Standards consist of specifications, drawings and manuals related to design, contracts, procurement and construction for new and existing sites, facilities and assets. Project Standards must be followed unless an approved variance is in place. They communicate all regulatory and applicable code requirements and are identified by:

  • All work associated with modifications made to all sites, facilities or assets, new or existing, and include calculations, policies and procedures related to the modifications.
  • Any change to assets or facilities requiring P&ID or drawing modifications.
  • Asset or facility repairs that require a re-evaluation of the system, such as welding, recoating, changes to station sizing, etc. Does not include Replacement-in-Kind, general operational maintenance, etc.
  • All testing required before the pipeline or piping system can be commissioned/recommissioned.

Site-Specific Procedures

Site-Specific Procedures are documents that apply to a specific location or department and include Operating Procedures, Maintenance Procedures and Emergency Response Plans. Site-Specific Procedures must be followed unless an approved variance is in place and must be developed, maintained and annually reviewed.


Note: All new procedures or modifications to existing procedures must have the appropriate approvals, as designated by Operations Leadership, before they will be added or changed in  WIMS. Knowledge Services provides document control support to the Operating Areas for the Site-Specific Procedures library.
