Definition Proactive Measures

“Creating or controlling a situation by causing something to happen rather than responding to it after it has happened.”

The steps you undertake before an incident occurs which allows you to better mitigate its effects.

TestingPro-Active Measures

Pressure Testing (or Risk-based alternative) of pipeline and all components

-4 continuous hrs at 125% of max. operating pressure plus:-Visual inspection for leak or additional 4 hrs continuous testing at 110% of max operating pressure

-Using H2O or inert gas (low stress pipe)

Cathodic Protection & External Corrosion Control-Must be tested just prior to lowering the pipe into the ditch or submerging the pipe

Non-destructive Weld Tests

Recordkeeping-Test records must be maintained the entire time that the tested facility is in use

Special ConsiderationsPro-Active Measures

High Consequence Areas-Commercially navigable waterways-Concentrated populations centers (>50,000 people as of last U.S. Census) and has a population density of at least 1,000 people/mi2

-“Other” populated area, which means a place, as defined and delineated by the Census Bureau, that contains a concentrated population, such as an incorporated or unincorporated city, town, village, or other designated residential or commercial area

-“Unusually sensitive” areas (drinking water or ecological resource area that is unusually sensitive to environmental damage from a hazardous liquid pipeline release)

-Drinking water intake;-Source Water Protection Area (SWPA);-Location containing imperiled, T&E, or depleted marine mammal species, or an imperiled ecological community where the species or community is aquatic, aquatic dependent, or terrestrial with a limited range

High Consequence Areas (HCA)Special Considerations

Requires Pipeline Integrity Management Program- Elements of written program include:

- A process for identifying which pipeline segments could affect a HCA; - A baseline assessment plan;- An analysis that integrates all available information about the integrity

of the entire pipeline and the consequences of a failure;- Criteria for remedial actions to address integrity issues raised by

assessment & analysis;- A continual process of assessment and evaluation to maintain a

pipeline's integrity- Identification of preventive and mitigative measures to protect the HCA- Methods to measure the program's effectiveness- A process for review of integrity assessment results and information

analysis by a person qualified to evaluate the results and information

40 CFR 112 – Oil Pollution PreventionPro-Active Measures

Differs from requirements found in 49 CFR 195 in that 40 CFR 112 deals with bulk storage and internal handling of oil (i.e., facilities) not oil in transportation (e.g., railcars, trucks, and pipelines).

Require facilities to prepare and implement site-specific plans* to address three areas:

• Secondary containment and other engineered and procedural control measures

• Operating procedures, inspections and other administrative measures

• Countermeasures and clean up measures

*Type and complexity of plans determined by overall storage capacity of the facility (e.g., Spill Prevention Control and Countermeasures Plan versus Facility Response Plan)

40 CFR 112 – Oil Pollution PreventionPro-Active Measures

Highlights of SPCC Rule:

Facilities must utilize secondary containment or environmental equivalent” for all bulk oil storage containers which are defined as > to 55 gallons and must account for containment of 100% of single largest container in dike plus “adequate freeboard for precipitation”.

Security at facility must be sufficient to deter vandalism and acts of terrorism (e.g., fences, lights, cameras, locks, 24-hour staffing, etc)

Inspections must be conducted routinely (typically monthly) and include all tanks and appurtenances including , supports, pipes, dikes, handling areas, etc.

40 CFR 112 – Oil Pollution PreventionPro-Active Measures

Highlights of SPCC Rule Cont’d:

Training must be given annually to all “oil handling personnel”.

If facility oil storage capacity exceeds 1,000,000 gallons than Facility Response Plan (FRP) must additionally be prepared which incorporates all SPCC rules plus requires hazard analysis of worst case discharge and triannual drills and exercises to demonstrate efficacy of the plan.

Center for Toxicology and Environmental Health, LLC

Definition Reactive Measures

“Actions done in response to a problem or situation. Reacting to problems when they occur instead of doing something to prevent them.”

The steps taken after a release has occurred to minimize environmental exposure and liabilities.

Responding to An IncidentReactive Measures

Work the Plan- You’ve spent time, money and resources engaging in pro-active

measures. You’ve previously planned the work, now work the plan.- Internal notifications- External agency notifications - Corrective measures and stopping the source of the release- Mobilization of contractors and resources- Deployment of control and recovery assets- Organization, structure, and location of incident command- Coordination of response activities- System restoration/business continuity

PeopleResponse Priorities

Responsibility for 1st Responders, Employees & Contractors, and Community

- Constituent-specific OSHA established “Permissible Exposure Limit” (PEL) Time Weighted Average (TWA) which is the permissible concentration in air of a substance that shall not be exceeded in an 8-hour work shift or a 40-hour work week

- Constituent-specific ACGIH derived “Threshold Limit Values” (TLV) TWA which is the concentration for a normal 8-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect.

- Typically the primary concern when dealing with people is the route of exposure through inhalation. Exacerbated by fires, blow-outs and activities like vacuum truck recovery, transferring, lightering, etc which aerosolize particulates into the air.

- Other routes of exposure include: ingestion (drinking water, fish consumption) and contact dermatitis (exposure to surface water, sediment, and/or soils).

People – Air MonitoringResponse Priorities

Strategy- Incident details – Location (i.e. urban versus remote), type and amount of

product released and/or on fire, SDSs, description of the environmental impacts (i.e. soil, water), site air monitoring results.

- Receptors – Location in relation to unplanned release and/or fire (i.e. distance, down-wind/stream, up wind/stream), type of receptors (i.e. intermediate, commercial, industrial, farmland, residential, schools, daycares, hospitals, immune compromised individuals).

- Location Details – Urban versus remote, accessibility, weather conditions, flooding, run-off, inversions, exclusion zone boundary, private versus public land, aerial maps.

- Sample Methodologies – Equipment/Sample Media capability (i.e. range, resolution, specificity), availability, chemical interferences, previous results, data extrapolation, laboratory capabilities.

People – Air MonitoringResponse Priorities

Sampling & Monitoring- Real-time instrumentation vs. analytical- Rapidity vs. quality

- If not done and documented properly can yield results quickly but not provide you with the level of detail needed to support subsequent litigation.

Public Health Unit- Review data: issue advisories for beach closures, fish consumption,

evacuations, etc. Typically work with Federal, State, County Health Departments.

- Not stood up in every incident; depends on UC/IC whether it is warranted.

Center for Toxicology and Environmental Health, LLC

Shoreline AssessmentEnvironment

Shoreline Cleanup Assessment Technique (SCAT)- Evaluates oiling conditions;- Factors in shoreline types ;- Identifies sensitive resources;- Determines need for cleanup;- Recommends cleanup methods and endpoints; and,- Places constraints on cleanup if necessary, due to ecological, economic, or

cultural concerns

Rapid Assessment Technique (RAT)- Rapidly documents gross delineation of shoreline impacts and documents

unimpacted shorelines

Natural Resource Damage AssessmentResponse Priorities

Separate Activity from “Response”

Purpose is to compensate the public for injured natural resources

Natural Resources Have Value

The Government Holds Natural Resources in Trust for the Public- Trustees

Focus is on restoration of natural resources

Not punitive

Center for Toxicology and Environmental Health, LLC

Waste CoordinationResponse Priorities

Properly manage waste generation, handling, transportation, final disposition (e.g., recycling, disposal, beneficial re-use, etc)

Provide necessary documentation for “mass-balance” accounting- Penalties and fines are determined in part by the amount of material

released into the environment. Accounting for the amount of material recovered as part of the waste stream can potentially save you millions in fines.

AssetResponse Priorities

System Restoration and Business Continuity; resumption of “normal” operations

- Typically slowed by causation and/or criminal investigations (e.g., CSB, PHMSA, FRA)

- Know your rotation schedule and personnel. If you are working on the response, who is running the business and doing your “day job”?
