Okay, let’s tackle this. So Chuck Treleaven has a mix of skills in hazardous materials management, environmental consulting, and sales. He’s experienced in RCRA, Hazmat, and EHS, which are important in the oil and gas industry. However, his role seems to be more focused on sales and new business development. Location is Spring, Texas, which is not a major hub for the oil and gas industry. Considering his skill set and location, I’d estimate his rate to be on the lower side of the industry average. Based on national averages, experienced sales professionals in the oil and gas industry can charge $75-$125 per hour. However, hazardous materials consultants with his level of experience might charge higher rates, around $100-$150 per hour. Given the mix of skills and location, I’ll estimate around $100 per hour.
