Golf Course Pollution Prevention Guide

According to the Environmental Protection Agency (EPA), pollution prevention can be defined as: “The use of materials, processes, or practices that reduces or eliminates the creation of pollutants or wastes at the source.” Pollution prevention represents a shift away from the old school of thought, “pollution control,” in which waste was not dealt with until after it was generated. Through pollution prevention, we look at the processes that generate the waste to see if we can avoid creating a waste in the first place, or at least reduce the hazardous nature of the waste. When this is not possible, the next best solution to prevent wastes from having a negative impact on the environment is through careful management and recycling. This manual will help golf course maintenance staff identify areas where pollution prevention techniques can be applied in a practical manner. Each section presents a waste type common to golf courses accompanied by pollution prevention recommendations. Although the focus of this manual is on pollution prevention, regulatory information is given as necessary where it impacts pollution prevention practices and to illustrate how pollution prevention can help reduce regulatory requirements.https://scholarworks.uni.edu/iwrc_facbook/1008/thumbnail.jp

Compliance Calendar/Logbook for Bulk Gasoline Plants: Less than 19,999 Gallons/Day Throughput

EPA has new requirements for Gasoline Distribution Bulk Terminals, Bulk Gasoline Plants and Pipeline Facilities under 40 CFR Part 63 Subpart BBBBBB (NESHAP 6B) to reduce air pollution. This calendar has been developed to assist Bulk Gasoline Plants in complying with NESHAP 6B. Additional Iowa specific NESHAP 6B rules are discussed later.https://scholarworks.uni.edu/iwrc_facbook/1004/thumbnail.jp

Servo Motor Control Using Variable Frequency Drive

Variable Frequency Drive (VFD) refers to an adjustable-speed drive where alternating current electric motor can be controlled by changing the values of frequency and voltage. This process allows the motor to change its torque and speed, depending on the need or demand from the user. VFD is used in many different applications, ranging from small to big, while preserving all other relevant advantages. Some of these advantages that come with using VFD are better process control and regulation, extended equipment life, and reduced maintenance. The components of VFD are converter, DC bus, and inverter. We successfully integrated VFD with Programmable Logic Controller (PLC) using sequencer Instruction to have a complete control over the AC servomotor, and operate motor with change in frequency of VFD. In this poster, we will examine what VFDs are and their applications. The outcome has market demand, especially that VFD applications contribute significantly to different industries
