MESA has specialized in marine cleaning since the company’s inception. Projects have been
Conducted in the Ports of Long Beach and Los Angeles as well as the San Francisco Bay Area
ports. Cleaning operations have been successfully completed in cargo holds, tanks and bilges
enabling the vessels to meet inspection requirements and change of product standards.
MESA has the experience and equipment to handle all aspects associated with the cleaning
of marine vessels. Hydroblasting is one of the cleaning tactics utilized by MESA that can be
used for a number of marine and industrial cleaning situations. Hydroblasting uses high-pressure
water at 5,000 to 10,000 psi. Capabilities include but are not limited to, the removal of scale
from tank walls and floors, exchanger tubes, oil product lines, tower walls and trays. All of our
hydroblasting operators are highly trained and qualified to operate the high-pressure
hydroblasters. MESA continues to reliably serve the needs of the shipping industry from the
actual cleaning operation to the handling and disposal of vapors, liquids and solids.
Marine cleaning services include:
• Tankers • Confined Space Entry
• Barges • 24-Hour Turn Around
• Cargo Holds • Steam Cleaning
• Tanks and Bilges • Vapor Control
• Hydroblasting • Mobile Waste Water Treatment
Petroleum & Chemical Storage Tank Cleaning & Degassing
MESA has extensive experience and training to perform tank cleaning operations at
petroleum and chemical storage facilities. Turnkey service is our strong point when it comes
to cleaning, residue wash water management and waste minimization and recycling.
Combined with the recycling capabilities provided to us by our mobile wastewater treatment
unit, costs can be minimized by reducing water volume and disposal costs.
MESA owns and operates fully permitted thermal oxidation units which are used to provide
tank degassing services primarily to the petroleum industry at transportation, refining and
storage facilities. As mandated by the Air Quality Management District (AQMD), the
vapors collected within the void space above a liquid in a tank cannot be vented directly
to the atmosphere during either the loading or unloading of a tank. These vapors must be
removed from the tank during the operation and processed so that no potentially hazardous
condition is created in the surrounding environment. MESA’s thermal oxidizer ranges in
processing capacity from 1,000 SCFM to 3,500 SCFM. Tanks degassed include storage tanks
ranging from 1,000 barrels to 275,000 barrels. MESA can meet all tank cleaning needs from
heavy sludge clean out to refined product waste clean out. Services include:
• Fuel Storage Tank & Pipeline Cleaning
• Chemical Tank Cleaning
• Tank Degassing • Heavy Duty Cleaning & Hydroblasting
• Confined Space Entry • Vacuum Truck Services
• Tank Bottoms Removal and Disposal
Industrial Cleaning and Decontamination

covers a wide range of customers’ needs and scenarios. Programs have been successfully
completed involving the cleaning of equipment for a variety of clients.
MESA employs experienced personnel and maintains a full compliment of decontamination
equipment at our yard. This enables us to respond quickly to a scope of work with the
resources to conduct a cleaning program efficiently while continuing to be cost effective.

• Pavement Decontamination
• Surface Preparation
• Scrap Material Disposition
• Chemical Spill Cleanup
• Fire and Flood Cleanup
Contaminated Site Clean-up Technologies
Timely and cost effective closure of industrial sites requires careful, up front planning and
project management. MESA has extensive expertise in providing management and field
services for facility closures. Experienced personnel are on staff to evaluate the facility, plan
the approach, provide the equipment and manpower, manage the decontamination and
demolition activities and arrange for disposal and recycling of wastes.
Typically, multiple sources of contamination exist in an industrial facility as a result of
manufacturing and process operations and from the use and storage of regulated chemicals,
lubricants and solvents. In addition to production related wastes, hazardous materials can also
be generated during the demolition of the buildings themselves. MESA has the expertise and
knowledge to identify the nature and extent of all these potentially contaminated and
hazardous areas. The proper handling of hazardous, non-hazardous materials and demolition
debris will be evaluated from the initial site work to determine the best solutions for waste disposal.
As part of total site closure management, MESA will also appraise the potential hazards of the
facility to develop proper worker protection and pollution control procedures. Close coordination
with regulatory agencies ensures that all work is conducted in strict accordance with applicable
codes and ordinances.
The MESA group of companies has personnel with the combined experience and expertise to
conduct all phases of facility closure. Technically sound, innovative approaches and safe
operating practices have helped MESA maintain a competitive edge in conducting
Hazardous Waste Transportation and Management
The chief goal of hazardous waste transportation is to provide the service cost effectively while
minimizing the liability of the client. MESA provides services for the management and disposal
of diverse hazardous waste streams. MESA is a qualified and licensed hazardous materials hauler.
We offer waste generators a variety of disposal and transportation options for all forms of solid,
semisolid and liquid wastes in drums or bulk storage. Our fully permitted fleet of vehicles and

transportation needs of industry. Whether the waste requires special handling or packaging,
MESA has the transportation application available.
MESA is experienced in managing and transporting Non-RCRA and RCRA hazardous wastes
for numerous industrial clients. MESA can handle the profiling of the waste stream and determine
the most cost effective method for treatment or TSD Facility for disposal.
Solid wastes managed by MESA typically include; exhausted chemicals and catalysts, tank
bottoms, contaminated soils, metals and used absorbents. Liquids such as spent caustic and
acid solutions, petroleum hydrocarbons, waste water, emulsified oil and water and used solvents
are often disposed of at the request of the client. Substances successfully handled include
corrosives, oxidants, toxins, PCBs, cyanides, sludges, reactives and flammables.
