Asbestos Enforcement Program

There are a number of laws that govern how asbestos materials are to be handled in schools, public and commercial buildings, including buildings that are to be demolished or undergoing major renovations. The laws that govern asbestos management and removal under the Environmental Protection Agency include: the Asbestos Hazard Emergency Response Act (AHERA), the Asbestos School Hazard Abatement Reauthorization Act (ASHARA) and the National Emission Standards for Hazardous Air Pollutants for Asbestos (NESHAP). The Occupational Safety and Health Administration (OSHA) regulates exposure to asbestos in the workplace.

SAN FRANCISCO -- The U.S. Environmental Protection Agency recently fined three Arizona charter school operators a combined total of $27,480 for alleged Asbestos Hazard Emergency Response Act (AHERA) violations

what is asbestos
What is Asbestos?

Asbestos is the name given to a group of naturally occurring

minerals used in certain products, such as building materials and vehicle brakes, to resist heat and corrosion.

Asbestos includes:

- chrysotile

- amosite

- crocidolite

- tremolite asbestos

- anthophyllite asbestos,

- actinolite asbestos

- and any of these materials that have been

chemically treated and/or altered.

  • A naturally occurring mineral
  • Added to building materials because of its good insulating, strength, sound-proofing, fireproofing and corrosion-resistance properties
slide11

Why is Asbestos a Hazard?

Asbestos is made up of microscopic bundles of fibers that may become airborne when disturbed. These fibers get into the air and may become inhaled into the lungs, where they may cause significant health problems. Researchers still have not determined a “safe level” of exposure but the greater and the longer the exposure, the greater the risk of contracting

an asbestos related disease.

Some of these health problems include:

- Asbestosis

- Mesothelioma

- Lung Cancer

asbestos health effects
Asbestos Health Effects

Asbestos is a problem when it is disturbed and fibers are released into the air.

why is asbestos a hazard
...Why is Asbestos a Hazard?

Asbestosis: a lung disease first found in naval shipyard workers. As asbestos fibers are inhaled, they become trapped in the lung tissue. The body tries to dissolve the fibers by producing an acid. This acid, due to the chemical resistance of the fiber, does little to damage the fiber, but may scar the surrounding tissue. Eventually, this scarring may become so severe that the lungs cannot function. The latency period is often 25 - 40 years.

Mesothelioma: a cancer of the pleura ( the outer lining of the lung and chest cavity) and/ or the peritoneum ( the lining of the abdominal wall). This form of cancer is peculiar because the only known cause is from asbestos exposure. The latency period for mesothelioma is often 15-30 years.

* Latency period - the time it takes for the disease to develop

...Why is Asbestos a Hazard?

Lung Cancer: Asbestos is a contributing factor of lung cancer. The effects of lung cancer are greatly increased by cigarette smoking (by about 50%). Cancer of the gastrointestinal tract can also be caused by asbestos. The latency period for cancer is often 15-30 years.

* Latency period - the time it takes for the disease to develop

when is asbestos a hazard
When is Asbestos a Hazard?

Asbestos is not always an immediate hazard. In fact, if asbestos can be maintained in good condition, it is recommended that it be left alone and periodic surveillance performed to monitor its condition. It is only when asbestos containing materials (ACM) are disturbed or the materials become damaged that it becomes a hazard. When the materials become damaged, the fibers separate and may then become airborne. In the asbestos industry, the term ‘friable’is used to describe asbestos that can be reduced to dust by hand pressure. ‘Non-friable’means asbestos that is too hard to be reduced to dust by hand. Non-friable materials, such as transit siding and floor tiles are not regulated provided it does not become friable. Machine grinding, sanding and dry-buffing are ways of causing non-friable materials to become friable.

asbestos national emission standard for hazardous air pollutants
Asbestos National Emission Standard for Hazardous Air Pollutants

The purpose of the Asbestos National Emission Standard for Hazardous Air Pollutants (NESHAP) Program is to protect public health from exposure to regulated asbestos-containing material (RACM) during NESHAP facility renovation/demolition activities, asbestos removal, transport and disposal, closely monitoring those activities for proper notification and asbestos emissions control.

Asbestos is known to cause cancer and other respiratorydiseases in humans.

Under Section 112 of the Clean Air Act (CAA), Congress gave the U.S. Environmental Protection Agency (EPA) the responsibility for enforcing regulations relating to asbestos renovations and demolitions activities. The CAA allows the U.S. EPA to delegate this authority to state and local agencies. Even after the U.S. EPA delegates responsibility to a state or local agency, the U.S. EPA retains authority to oversee agency performance and to enforce the Asbestos NESHAP regulations as necessary.

The Asbestos NESHAP program in Arizona is enforced by federal, state, and county Asbestos NESHAP agencies.

AHERA

The Asbestos Hazard Emergency Response Act (AHERA), a provision of the Toxic Substances Control Act, became law in 1986.

AHERA requires local education agencies to inspect their schools for asbestos-containing building material and prepare management plans to prevent or reduce asbestos hazards.

Public school districts and non-profit private schools (collectively called local education agencies) are subject to AHERA's requirements. This includes charter schools and schools affiliated with religious institutions.

asbestos regulations1
Asbestos Regulations

Asbestos Hazard Emergency Response Act (AHERA) effective 1987.

  • Applies to all public and private schools or Local Education Agencies (LEA)
  • Requires inspection, training, notifications, labels, Designated Person, and a Management Plan
  • Designated Person assigned to keep management plan and associated requirements up to date.
how do schools comply with ahera

The rules implementing AHERA are published in the Code of Federal Regulations, Chapter 40, Part 763, Subpart E. The AHERA rules require local education agencies to take actions to:

  • Perform an original inspection and re-inspection every three years of asbestos-containing material;
  • Develop, maintain, and update an asbestos management plan and keep a copy at the school;
  • Provide yearly notification to parent, teacher, and employee organizations regarding the availability of the school's asbestos management plan and any asbestos abatement actions taken or planned in the school;
  • Designate a contact person to ensure the responsibilities of the local education agency are properly implemented;
  • Perform periodic surveillance of known or suspected asbestos-containing building material;
  • Ensure that properly-accredited professionals perform inspections and response actions and prepare management plans; and
  • Provide custodial staff with asbestos-awareness training.

slide45

Proper methods for dealing with Asbestos

The AHERA schools rule rarely requires the removal of asbestos materials.

Proper asbestos management begins with a comprehensive inspection by qualified, trained and experienced inspectors, accredited through an EPA or state-approved training course.

Inspecting the condition of asbestos materials – initially with AHERA-accredited inspectors and at least semi-annually with trained custodial or maintenance staff – is extremely important so that changes in the material’s condition - damage or deterioration, can be detected and corrected before the condition worsens.

Only an AHERA-accredited management planner – an asbestos professional with proper training, qualifications, and experience – is authorized to advise school officials on which response action is appropriate for a particular situation.

slide46

What Should My School District Be Doing?

Under the AHERA schools rule, each local education agency (LEA, which means a school district or private school) must take the following asbestos-related actions:

1 Designate and train a person to oversee asbestos-related activities in the school system.

2 Inspect every school building for “friable” and “nonfriable” asbestos-containing building materials.

3 Prepare a management plan for managing asbestos and controlling exposure in each school.

4 Consult with accredited inspection and management professionals to identify and carry out whatever asbestos actions are necessary and appropriate to protect health and the environment. These actions or methods must be documented in the management plan.

5 Notify the public about the asbestos inspection and the availability of the asbestos management plan for review.

6 Use only properly accredited persons to conduct inspections, to develop the asbestos management plan, and to carry out the appropriate response actions.

7 Keep records of all asbestos related activities in the plan and make them available for public review.

slide47

What Does the LEA

Designated Person Do?

This designated person must meet certain training requirements, and serves as the single point of contact for public information about asbestos-related activities in the LEA. He or she is responsible for:

• Ensuring that initial asbestos inspections, re-inspections every three years, and semi-annual surveillance activities are conducted properly by qualified personnel.

• Including results of the inspection in the management plan. The plan must identify all asbestos-containing building materials found in schools and recommend actions for dealing with asbestos hazards.

• Preparing a management plan (for schools built after October 12, 1988) for submission to the appropriate state Agency prior to the school being used as a school building. The management plan should be maintained and updated with records of response actions, periodic surveillance of asbestos containing materials (ACM) and all re-inspections.

slide48

What Does the LEA

Designated Person Do?

• Making sure that custodial and maintenance workers receive required safety training and information about the location of asbestos-containing materials in their school. Warning labels must be posted in all routine maintenance areas, such as boiler rooms, where asbestos-containing building materials are found.

• Ensuring that response actions specified in the management plan are carried out according to the plan’s timetables. The regulations require that all LEAs were to begin to carry out their management plans no later than July 9, 1989.

• Seeing that all asbestos records required by the regulations are accurately maintained.

• Informing all teacher, parent and employee organizations at least once a year about the asbestos activities in each school and about the availability of the management plan for their review.

slide49

Who Is Responsible for Making AHERA Work?

EPA conducts compliance inspections of a sample of schools each year to make sure they are obeying the law. The Agency is responsible for insuring that schools comply with AHERA and it will investigate reported violations.

What Can I Do

Step One: Awareness

Your first step is to make sure your school has prepared an asbestos management plan as required by AHERA.

Step Two: Minimize Disturbance

Find out which materials in your school contain asbestos (AHERA MANAGEMENT PLAN FOR MY SCHOOL ). Once you know where asbestos is, use special care to insure that any day-to-day activities, such as repair or maintenance work, do not disturb the material.

Occupational Safety and Health Act of 1970

You have the right to a safe workplace. The Occupational Safety and Health Act of 1970 (OSH Act) was passed to prevent workers from being killed or seriously harmed at work. The law requires employers to provide their employees with working conditions that are free of known dangers. The Act created the Occupational Safety and Health Administration (OSHA), which sets and enforces protective workplace safety and health standards. OSHA also provides information, training and assistance to workers and employers. Workers may file a complaint to have OSHA inspect their workplace if they believe that their employer is not following OSHA standards or that there are serious hazards.

slide61

Workers' rights under the OSH Act

Workers are entitled to working conditions that do not pose a risk of serious harm. To help assure a safe and healthful workplace, OSHA also provides workers with the right to:

Ask OSHA to inspect their workplace;

Use their rights under the law without retaliation and discrimination;

Receive information and training about hazards, methods to prevent harm, and the OSHA standards that apply to their workplace. The training must be in a language you can understand;

Get copies of test results done to find hazards in the workplace;

Review records of work-related injuries and illnesses;

Get copies of their medical records;

slide62

Employer Responsibilities

Employers MUST provide their employees with a workplace that does not have serious hazards and follow all relevant OSHA safety and health standards.

Employers MUST also:

Inform employees about hazards through training, labels, alarms, color-coded systems, chemical information sheets and other methods.

Keep accurate records of work-related injuries and illnesses.

Perform tests in the workplace, such as air sampling required by some OSHA standards.

Provide hearing exams or other medical tests required by OSHA standards.

Post OSHA citations, injury and illness data, and the OSHA poster in the workplace where workers will see them.

Notify OSHA within 8 hours of a workplace incident in which there is a death or when three or more workers go to a hospital.

Not discriminate or retaliate against a worker for using their rights under the law.

slide63

Proper methods for dealing with Asbestos

  • Developing and carrying out a special maintenance plan to insure that asbestos containing materials are kept in good condition. This is the most common method when the materials are in good condition at the time of initial inspection.
  • Repairing damaged pipe or boiler covering, which is known as thermal system insulation.
  • • Spraying the material with a sealant to prevent fiber release – a process called encapsulation.
  • • Placing a barrier around the materials, which is known as an enclosure.
  • • Removing asbestos – under special procedures.
  • maintenance plan to insure that and other

Response actions – encapsulation, enclosure, and removal – and sometimes the second method – repair – must be done by accredited asbestos professionals.
