 Emergency Support Functions The University City Fire Rescue has been tasked with updating the emergency operations plan (EOP) for the community. Your assignment is to draft one of the 16 emergency support functions (ESFs) for the EOP. Your ESF assignment should be a minimum of one page, but no more than three pages. It must pertain to one of the 16 ESFs identified by FEMA. In addition, you must explain the role the fire service has within the EFS you choose, while including the different primary and supporting agency roles as well. Finally, be sure to identify and summarize requirements for ESF development and operations. To assist you in drafting the ESF, click here for the demographics of the University City Fire and Rescue, as well as here for the ERP for Hazardous Material. After opening the ERP for Hazardous Material and reading through it, you will begin creating your own chosen ESF. When creating your ESF, be sure that it is unique to your chosen requirement. If you have any questions regarding the assignment, your instructor is available. Information about accessing the grading rubric for this assignment is provided below. 

To prepare for this assignment, you will need to review the case study on page 255 of your textbook. Analyze the information from the case study, and be sure to address the following information in your response to the case study: 

1. Describe the advantages to using paid and volunteer staff for life safety and fire prevention programs and the problems that might occur between newly hired staff in Christmas Valley and the neighboring jurisdiction, where code compliance inspections were previously done by emergency responders.
    
2. What qualifications might be necessary for these staff members and how would you go about finding out about state or national training requirements or certifications?
    
3. How would you go about developing a training program for life safety and fire prevention staff? Whose support would be necessary, and how would it be funded?
    

Your case study should be at least two pages in length and MUST be properly cited   in APA style. A minimum of two references are required. 

 Question 1 . see attached 

Question 2 . Write a 1,050- to 1,400-word paper that identifies the effects that people have on the hydrological cycle and the consequences of these effects. In the paper, include the following: 

• Describe the water cycle, including sources of usable freshwater and renewal times for rivers, lakes, and ground water.
• Explain how wetland destruction and creation of impervious surfaces through urban development affect the water cycle and contribute to flooding.
• Explain some pros and cons to using levees for flood control and whether it is in the best interest of communities to rely of levees to prevent flooding.
• Explain how dams influence the hydrologic cycle and whether they are viable option for long-term flood control, water supplies, or power generation.
• Explain three issues associated with irrigation, including whether current rates of aquifer use are sustainable. 

Include at least three references in addition to the text, formatted consistent with APA guidelines.

 Create a presentation with a minimum of 10 slides about the uses and limitations of the U.S. Food & Drug Administration’s (FDA) requirements on product labeling for public safety. Include a discussion of a recently published article (within the last 12 months) that addresses product labeling. Only use information from reliable sources; DO NOT use information from unmonitored websites, such as Wikipedia, is not acceptable. Be creative, and add photos, images, or other supplemental graphics to support your presentation. Ensure that you use images from the public domain or creative commons. Be sure to cite any sources used in a references slide by using proper APA style. You may also use the slide notes function to explain slide contents as necessary. 

The following are ideas for topics that you may want to address: 

1.the purpose of product labeling

2. product labeling requirements

3. limitations of product labels

4. pesticide product labeling

5. federal food and drug requirements for labeling.
