PQS TRAINING PROGRAM REMOTE FACILITIES

Transcription

1 PQS TRAINING PROGRAM REMOTE FACILITIES PURPOSE GENERAL The Remote Facilities Professional Qualifications Standards (PQS) Training Program was established to guide operators through their journey of becoming a fully trained Operator at the Encina Wastewater Pollution Control Facility (EWPCF). It is the Encina Wastewater Authority s (EWA s) goal to provide training programs that increase the knowledge and skills of employees while enhancing opportunities for advancement within the organization. The Remote Facilities PQS provides staff with uniform knowledge regarding operation of the pump stations and Carlsbad Water Recycling Facility. PROCEDURE 1. Start Date The Operator will be issued a PQS start date from the PQS Coordinator. This PQS must be finished during the Operator s rotation to Remote Facilities. 2. PQS Training Guide The PQS Coordinator will provide the operator with a PQS Training Guide. The Operator is responsible for the completion of the program. Each question in the Training Guide needs to be reviewed with their mentor or supervisor. If the mentor or supervisor feels the operator has a good understanding of the subject matter, they will sign the question as being completed. The Operator can personalize each section in the Training Guide with notes, acronyms, pictures, or anything which will help them understand the concept. The Operator is responsible for their Training Guide, which is necessary to document successful completion of the PQS, and is a valuable tool for future reference. If the Operator is uncertain of where to find information relevant to the PQS questions, they should ask their mentor or supervisor for assistance. As each section is signed as completed, the Operator is to bring the Guide to the PQS Coordinator who will update their performance tracking status. PQS - Remote Facilities Page 1 of 24
