3 Overview By collecting water that comes off of vehicles and equipment, a wash bay is both practical and environmentally beneficial. All employees must be aware of the hazardous materials that collect on vehicles and can be washed into a wash bay collection system. It is never a good idea and at most locations illegal to drain untreated wash water into a sewer or storm drain system. To dispose of wastewater from a wash bay, you can: Store the used water and dispose it at a wastewater station. Appropriately treat the water before sending it into a sewer. Recycle wastewater. Wash water can negatively impact surface and underground sources of drinking water. Wash bays prevent underground and surface water contamination. Version 1.0 3

4 Tip Vehicle wash water contains oil, grease, paint chips, brake dust, rust, detergents, cleaners, road salts and other chemicals that can contaminate drinking water. Work Instruction Control water and sludge from cleaning equipment at drilling facilities and locations. Collect sludge and water from cleaning equipment in a wash bay and storage devices. Wash bays and storage devices must meet legal, environmental and safety requirements. Licensed contractors can dispose of sludge and water collected in wash bays. Procedures and schedules for waste water disposal are determined by local management and designees assisting the process. As part of the procedure, require contractors to test waste before pumping it into their tank. Later, if a contractor has hot waste that is possibly illegal or need special handling, Boart Longyear can prove its waste is not the cause. Water pollutants are eventually carried to the ocean. 4 Version 1.0

5 Activity and Actions To dispose of wash bay sludge and water consider the following: Verify your wash bay and sludge collection storage area meets legal and other requirements. Identify and use a licensed contractor to dispose of sludge, oily and contaminated water. Discussion Require contractors to test their tank before and after pumping off wash bay fluid. When a contractor acquires hot chemicals that require special treatment, they can tell if the chemicals came from a Boart Longyear facility. Provide documentation listing vendors and contact information, which shows proper disposal of wastewater. After washing vehicles and equipment, dispose of wastewater in an ecological way. Contaminated ground and surface water often ends up in the food supply. Version 1.0 5

6 Think for a Moment Wash water contains oil, grease, metal paint chips, brake dust, rust, detergents, cleaners, road salts and other chemicals that can contaminate drinking water. Soaps add ammonia, phenols, dyes and acids. All soaps, even biodegradable ones, contain surfactants, which are detrimental to fish and wildlife. Surfactants, even at even extremely low concentrations, can prevent aquatic and other species from reproducing. Wash water can impact surface waters and underground sources of drinking water while destroying organisms necessary for proper functioning of septic systems. Wash water can also percolate through the soil and enter aquifers. In regions with snow during the winter, vehicles and equipment are washed to remove road salt. Salt is harsh on vehicles and road salt can run off into streams, lakes and wells. Chloride from road salt is also toxic to aquatic life. Manage and store wash water in holding tanks for offsite treatment. Onsite, discharge wash bays according to local laws and environmental practices. The critical point is to prevent untreated wastewater from entering storm water drains, ditches, creeks, rivers, bays and oceans and underground. The company and employees can be held liable for incorrectly disposal of wash bay waste. Protect yourself, the company and environment and follow proper procedures. It s critical! Always prevent wastewater from entering our water systems. 6 Version 1.0
