9.1 Hazardous Materials including Hazardous Waste

• Many waste materials generated during the course of work at the WTE Facility has the potential for being classified, through testing and analysis, as a hazardous waste. Contractor Health and Safety Programs required in the Service Agreement address the handling of these hazardous waste materials.

• For Companies providing spill response (containment) and clean-up of materials determined to be a hazardous waste must be handled by individuals who have received training in accordance with State and Federal Hazardous Waste Regulations (40 CFR 265.16 and OSHA Standard 1910.120

(q) or (p)(8)).

• Trained contractors will handle hazardous waste as described in the Scope of Services, at the WTE Facility by placing the material into City-approved or provided containers and then moving them to an approved on-site storage location as specified by WTE Facility management. At no time shall any hazardous waste be placed into storage or removed from the WTE Facility without authorization.

• Contractors are required to inform City management during the EHS orientation if they anticipate that their work will generate hazardous waste onsite. Contractors are required to inform City WTE Facility management when they actually generate any hazardous waste (notify during same shift that waste is generated). For multi-day jobs where hazardous waste generation is expected over an extended period (e.g., entire bag house change out) then only an initial notification of hazardous waste generation is required.

CITY OF TAMPA MCKAY BAY WASTE-TO-ENERGY FACILITY

CONTRACTOR ARSENIC, LEAD, CADMIUM, AND HEXAVALENT CHROMIUM NOTICE

The below information provides a background of general potential for heavy metals exposure that Contractors should be aware of while performing work at the McKay Bay Waste-to-Energy Facility (WTE Facility). Contractors will be required to comply with all applicable federal, state and local laws, including but not limited to U.S. Occupational Safety and Health Administration (OSHA) regulations. The purpose of this Notice is to inform Contractors of the potential for exposure to arsenic, lead, cadmium, and hexavalent chromium at the WTE Facility. It is not intended to be legal guidance on the federal, state and local laws that may apply to the Contractor’s operations.

Contractors will be responsible for maintaining their own industrial hygiene and respirator programs, as required by OSHA, and are encouraged to review potential exposure compared to the OSHA Permissible Exposure Limits (PELs) for lead, cadmium, arsenic, silica, hexavalent chromium, and noise. The City of Tampa (City) will provide any such industrial hygiene information as is readily available to assist the Contractor in making informed decisions for the development of said procedures.

In accordance with OSHA regulatory requirements, employers are responsible for performing exposure monitoring on a representative number of employees and job types. OSHA states that enough air sampling must be done to enable each employee's exposure level to be reasonably represented by at least one full shift (at least 7 hours) air sample. Additionally, OSHA states that these air samples must be taken under conditions, which represent each employee's regular, daily exposure.

The Facility operates 24-hours/day seven days/week. City employee exposures can be broken out into two categories: (i) daily plant operations; and, (ii) outage activities. Outage activities occur throughout the company on a schedule where one or more boilers are shut down and maintenance is performed on them. Outage activities occur for a total period of time ranging from approximately 12-30 days/year/plant. Factors that control outages, beyond what is annually scheduled as part of preventative maintenance, are operational performance and forced downtime. Most outage tasks are performed inside the boiler cavity with the engineering controls of the induced-draft fan operating. Pre-work activities, may include water-wash cleaning of the boiler cavity with high-pressure nozzles (10,000 psi) and percussion blasting which removes ash-containing metals from the working surfaces prior to employees engaging in specific activities. The use of engineering controls and work practices has had an impact at reducing employee exposures. The tasks performed during outage or maintenance activities are where personal exposures are expected to be the greatest. However, the time plants are in outage represents about 8% of total operating time. Eleven months of the year (time plants not in outage activities) are considered when City employees could have a “regular, daily exposure” as defined by OSHA when exposure monitoring is to be performed. During daily plant operations for more than 11 months/year, these

condition are well documented to be static, and generally below established action levels and permissible exposure limits.

Many years of exposure monitoring data have been collected since the initial assessments were made at plant commissioning. The exposure monitoring data collected throughout the industry have further defined where actual or potential employee exposures exist while specific work tasks are performed. The years of data have been used to implement engineering controls and work practices to reduce, control, or eliminate worker exposures. The use of respiratory protection has been selected for specific work activities or tasks to supplement engineering and work practice controls and to further reduce worker exposures where the potential of exceeding the OSHA PEL exists. OSHA permits the use of the assigned protection factors of the selected respiratory protection to control worker exposures to below the PEL when a 1) fully implemented Respiratory Protection program (OHS-US-219 Respiratory Protection) is in place and 2) after engineering controls and work practices have been implemented. In determining the workers full shift exposure, the time period respirators are used is averaged with exposure levels when respirators are not worn to determine the employee's daily TWA exposure.

The City has work task exposure monitoring data that shows exposures greater than the OSHA action level or PEL. Based on exposure monitoring data, specific work tasks have had, engineering controls, work practices and respiratory protection selected to reduce, eliminate or control worker exposures.

OSHA permits the use of respiratory protection to reduce exposures to below regulated limits. OSHA states that employers must repeat exposure monitoring at 6 and or 3-month intervals when specific exposure levels have been reached or exceeded. OSHA also states that if employers can collect additional exposure monitoring data at least seven days apart and demonstrate that they are below the action level, then future air sampling can be suspended as long as no new process changes occur. Collecting air sampling during an activity or task that exceeded the action level or PEL at least seven days after the initial test is not feasible were they were collected during an outage. Outage activities are for a finite period of time and in some cases the task may not be performed again for an extended period of time beyond 3 or 6 months. Based on the nature of outage work, it is not feasible to perform air monitoring seven days after the measure exposure or in most cases at the three-month or six-month frequencies listed in the standard. Because Facility employees have a normal, daily exposure for more than eleven months during the year that is below the action level additional exposure monitoring is not necessary.

The regulatory framework permits employers to suspend air sampling when two air-sampling events, taken at least 7 days apart, are below the action level. The City, instead of using this regulatory approach for stopping to collect air samples, is using a combination of air monitoring data, historical monitoring data, and objective data to make decisions. When employees perform specific work tasks, they can generate exposures that may or may not exceed the AL or PEL. For tasks where there has been identified an actual or potential exposure, engineering controls, work practices, and respiratory protection have been identified and captured in a JHA and listed in the Safety Rules Book.

The City will perform additional exposure monitoring whenever there is a production, process, or control change, which may result in new or potential exposure, or whenever there is any other reason to suspect a change, which may result in new or potential exposure.

General Contractor Health and Safety Requirements Related to Arsenic, Lead, Cadmium, and

Hexavalent Chromium at the McKay Bay WTE Facility

Personal Hygiene The power plant ash contains varying concentrations of heavy metals (e.g., lead, cadmium, inorganic arsenic) and silica. Contractor’s employees are required to thoroughly wash their hands and face before eating or drinking and before leaving the Facility.

Protective clothing is also necessary to protect from ash-laden areas (e.g. coveralls).

Contractor’s clothing and boots containing ash shall be removed or cleaned with a vacuum fitted with a high-efficiency particulate air (HEPA) filter before leaving the Facility.

Contractors may not enter lunchrooms or administrative areas with dirty or dusty protective work clothing or equipment.

Respiratory Protection City employees are required to wear respiratory protection while performing specific tasks or while working in specific environmental conditions. Respiratory protection selection is based on air sampling data collected during these tasks and in various conditions.

Welding and/or burning of ash-laden materials may expose the welder to inorganic arsenic, lead, and cadmium, and hexavalent chromium if working with certain steel alloys, especially stainless steel.

Full-face respirators and proper eye protection must be worn at all times during welding/burning activities associated with ash-laden materials.

Contractors shall wear respiratory protection in all posted areas.

Contractors must select the appropriate respiratory protection for their employee’s exposures.

Contractors are welcome to review the City’s industrial hygiene air sampling data to assist in selecting the appropriate respiratory protection. However, the City’s air sampling data may not be relevant to the tasks the Contractor will be performing. Contractors are required under OSHA Standards to assess their employees’ exposure(s) to air contaminants. Contractors wanting to conduct air sampling on the McKay Bay RTE Facility site must coordinate these activities with the Facility before they begin. A contractor air sampling plan will be required and approved by the City before any air sampling is performed. An example of an approved air sampling plan and associated field observation sheets can be provided upon request.

Contractors using respiratory protection are required by Federal or State OSHA to have a respiratory protection program.

In accordance with State or Federal OSHA Standards, Contractors wearing tight fitting respirators must not have any facial hair, including a one day’s growth, between the face-to-respirator seal or at a length to impact the exhalation valve operation.

These procedures comply with OSHA regulations 12CFR1910.1025, 29CFR1925.62, 29CFR1910.1027, 29CFR1926.63, 29CFR1910.1018, 29CFR1926.1118, 29CFR1910.134, 29CFR1926.103, 29CFR 1910.1026, & 29 CFR 1926.1126.

Part Number: 1910 Part Title: Occupational Safety and Health Standards Subpart: Z Subpart Title: Toxic and Hazardous Substances Standard Number: 1910.1018 App A Title: Inorganic Arsenic Substance Information Sheet
