Running head: GENERAL CONSIDERATION FOR OPERATION MEE 6501- General Consideration for Operation Malcolm Logan Columbia Southern University November 18, 2019 Dr. Heather Frost 1 GENERAL CONSIDERATION FOR OPERATION 2 General Consideration for Operation Abstract Dallas rail tank car is a painting and repair company based in Texas, the US, seeking permission to set up a painting spot. Texas, environment protection agency, has requested the company to apply for a permit by rule (PBR) document to proceed with their construction. Dallas rail tank car company gave a statement detailing the proportions of volatile organic compounds (VOCs) and exempt solvent (ES) they intend to use and the general layout of the firm to qualify for the PBR certification. The company employs 10 gallons of coating and 2 gallons of solvent per rail tank car for the lining. Additionally, the company intends to apply the coating to the interiors of two rail car tanks each day. Lining curing will follow with two rail tank cars passing the treatment every day. Both coating and curing will take five working hours a day and four workdays a week. The company finalizes with plans of proper ventilation of the site and careful disposal of wastes. The operational emission rates of VOC are projected to increase which can harm human health based on the environmental health and safety (EHS) strategies. Also, the operational emission rates surpass that of the DEQ due to the increased emission of the Dallas rail tank in a value which is higher at 0.407lb/hr. GENERAL CONSIDERATION FOR OPERATION 3 PBR Evaluation Texas commission on environmental quality sets the thresholds for consideration of the issue of a permit by rule document (TCEQ, 2011). The company meets the threshold for review by emitting 5.8 pounds of VOC per hour, which is below the threshold limit of 6 pounds per hour. (TCEQ, 2011). That is 2.8lbs multiplied by 10 gallons of VOC in a day, then dividing by 5 hours as the company spends 5 hours a day in the coating. TCEQ (2011) further sets the minimum face velocity in an exhaust fan at 100ft per minute. Dallas rail tank car company meets this threshold with a face velocity 6ft per minute higher at 106ft per minute. The figure is reached by first subtracting the makeup air flow rate (5760ft3/min) from the exhaust flow rate (10000ft3/min) to get 4240ft3/min. There are two flow areas of 20ft2 each, which are added to get 40ft2. The total flow rate of 5760ft3/min is then divided by 40ft2 to get a face velocity of 106ft per minute. Dallas rail tank Car Company also meets the threshold for maximum filter velocity of 250ft per min as stipulated by TCEQ (TCEQ, 2011). The company registers a filtering velocity of 250ft/min obtained by dividing the exhaust flow rate (10000ft3/min) by the total filter area of 40ft2. The company also meets the short term emission threshold of 1.0 pounds per hour as required by the TCEQ by registering 0.407lb/hr. The company also meets the long term emission threshold of 1.0 tons/yr by registering a lower value of 0.5083tons/yr. Since the primary source of heat is natural gas with a known chemical composition of sulfur (IV) oxide, carbon (II) oxide, volatile organic compounds, and nitrogen oxides, there is ease in calculating the emission amount during heating. Hourly emission is calculated by multiplying the standard weight of individual compounds in natural gas by 2.1 MMBtu/hr and then dividing the value with the typical value for natural gas 1021 Btu/SCF (TCEQ, 2011). The individual value is then added to get the hourly emission, which is 0.407lb/hr in Dallas’s case. The company arrived at the amount of the long term emission by multiplying GENERAL CONSIDERATION FOR OPERATION 4 individual short term emission value by the total operational duration during the year 2500hrs (TCEQ, 2011). The value was then converted to tons by dividing it by 2000lbs. 0.5083tons/yr was the total of the individual long term emission of natural gas compounds. Looking at environmental health and safety concerns, Dallas rail tank Car Company constructed spray booths that enabled safe containment of the VOCs in the paints. The spray booths also facilitated in-house cleaning of spray guns, which the exhaust fan helped in the safe disposal of spays through the filters. This helped minimize air pollution caused by such activities, limiting the chances of causing health problems to road users. The company made room for the incorporation of makeup air into the spray booths, which facilitated prompt air circulation in the spray booth. Finally, the company adhered to the use of verified sources of heat by using natural gas as stipulated by the TCEQ. The use of natural gas makes the calculation of emission easy as it has known chemical compounds that are measurable for regulating emissions. Operational Emission Rates The emission of the VOCs from the system has various impacts on the environment especially following the rates at which they get released. The first notable impact is the increased level of chlorofluorocarbons in the atmosphere which naturally depletes the ozone layer and result in challenges associated with reduced competence of the environment. Since the system emits gases at higher rates, it is a great challenge to the environment because the hydrocarbons, as well as other gases, increase in quantity which demeans the quality of EHS. Human health is also greatly impacted by the VOCs since the gases are possible toxic substances that reduce the competence and recommended approaches required in human health. The continued inhalation is a challenge since it reduces the competence and recommended healthcare. With fatigue and distress caused by increased levels of the gas, the health is compromised and the individuals are challenged especially regarding the needed GENERAL CONSIDERATION FOR OPERATION 5 policies of quality control. A good approach to the strategic healthcare control policy is by ensuring that the workers are not exposed to toxic chemicals. The risk of cancer is also seen in the VOCs emission from the work system since the tons are increasing. With an increased quantity of the emissions, the humans inhale them which causes irritation of the mucosa hence reducing the quality of the health of the individuals who get to interact in the setting. Qualitatively, occupational health and safety principles are not followed by the VOC since the work setting is not standardized and the challenges associated with the same are plenty. A needed approach to the required policies is the elimination of the number of gases in the atmosphere as recommended. A strategic approach requires that the interventions are followed in the elimination of the number of gases and the rate of emission. The proof of toxicity is based on the following: a. Annual hourly emissions Based on the quantity of VOCs emitted on a daily basis, the required hourly emissions based on a daily Gallons of VOC emitted daily: 10 which is 2.8lbs. Annually five hours a day: (10 x 2.8 x 365days) =10220lbs. Annual hourly emissions: (10220/5) = 2044lbs. The total velocity flow rate is 5760ft3/min The velocity flow per minute = (5760 ft3/min)/40ft2 = 106ft/minute. The production processing requires the use of natural gas. Hourly emission of natural gas is 0.407lb/hr. Considering the hourly emission for a year, the value culminates to 0.5083tons/yr. GENERAL CONSIDERATION FOR OPERATION 6 b. The report of the emissions of the gas annually indicates a higher value which violates the DEQ standards. Under normal circumstances, the DEQ ratings show that the value is 1021 Btu/SCF. With the increased level of emission and other advanced approaches that increase the quantity of the gas in the atmosphere, it can be considered a higher value which is .407lb/hr. the rate of flow indicates that the company should reduce the rates and ensure that emphasis is laid on better approaches which can reduce the level of emissions c. The potential emission with increased rates of the gas can be 0.500lb/hr due to a projected increase in the company working hours and rate. The major challenge is the issues that exist and other challenges which reduce the competence of the emission system. The DEQ policy, therefore, is violated due to the surpassing of the set value which should always be observed as recommended (TCEQ 2011).
