All questions are to be answered individually, does not require essay form. Explain the concept of Risk-Based Corrective Action (RCBA). Why is this concept used in hazardous waste remediation? Discuss the relationships between RCRA, CERCLA, SARA, and EPCRA. Why do you think there are so many different laws governing hazardous materials and hazardous waste? Discuss three waste minimization strategies that could be used by a small business classified as a small quantity generator. Provide examples for each strategy. Your response must be at least 150 words in length. What should prospective buyers of commercial property do in order to protect themselves from liability under CERCLA? Your response must be at least 150 words in length. A research lab uses acetone as a solvent for cleaning glassware. The spent solvent is consolidated into containers for disposal. Is this disposal subject to RCRA Subtitle C regulations? Explain how you reached your decision. Your response must be at least 300 words in length. What are some important considerations for selecting a transfer, storage, and disposal facility (TSDF)? Which ones should be first on the list when conducting an audit of a TSDF? Explain your choices. Your response must be at least 300 words in length.
An octave is defined as a doubling of the frequency. The claim is made that a low-pass Butterworth filter of order n has a roll-off (attenuation) of 6n dB/octave. Calculate the gain in dB for a second-order filter for the cut-off frequency itself, an..
100 lb of fluid food is heated by addition of 10000 btu of energy. if the food has initial temperature of 40degf and
a peripheral milling operation is performed on the top of a rectangular workpiece that is 650 mm long 50 mm wide and
An air cushion vehicle is supported by forcing air into the chamber created by a skirt around the periphery of the vehicle as shown in Fig. P3.106. The air escapes through the 1.7-in. clearance between the lower end of the skirt and the ground (or wa..
Design an SI engine operating on an four-stroke air-standard cycle using stoichiometric gasoline is to have a maximum cylinder pressure of 11,000 kPa at WOT. Inlet pressure can be 100 kPa without supercharging, or it can be as high as 150 kPa with a ..
Explain circumstances in which it is possible to improve maintainability to counteract poor reliability, and also identify circumstances where this approach is unrewarding.
A large explosion occurs on the earth's surface producing a shock wave that travels radially outward. At a particular location, the Mach number of the wave is 2.0. Determine the induced velocity behind the shock wave. Assume standard conditions.
A 0.453-Kg mass attached to a light spring elongates it by 7.87mm. Determine the natural frequency of the system.
Determine the minimum value of R and the corresponding value of x
Determine the tangential force F and the normal force N acting on the collar when u. = 45°, if the force F maintains a constant angular motion u = 2 rad>s.
You want to know if you should replace the existing machines, which has a Cpk of 1.0. You decide to determine the Cpk for the new machines and make a decision on that basis.
A constant force of F is applied to a block of weight w located on an inclined surface with angle of and friction coefficient u. A spring is acting on the block with constant K. if initially spring was compressed by distance d. Find velocity of block..
