Module 1: Background Of an Inspector Flashcards
Erosion key definition
The process–action of water, wind and other weather condition—cause soil particle displaced.
Type of erosion
- Wind erosion
- Raindrop erosion
- Sheet erosion
- Rill and gully erosion
- Stream and channel erosion
FACTOR THAT IMPACT WATER EROSION
- Climate
- Soil erodibility
- Length of flow
- Slope of the land
- Erosion control BMP
- Sediment control BMP
WHAT FACTOR AFFECT SEDIMENTATION?
- Particle size
- Flow velocity
- Basis of how sediment containment system function
WHAT FACTOR AFFECT SEDIMENTATION?
- Particle size
- Flow velocity
- Basis of how sediment containment system function
HYDROLGY
Study of water of the earth:
1. Occurence
2. Circulation
3. Distribution
4. Chemical and physical properties
5. Reaction with the environment
6. Relation to living thing
FACTOR AFFECTING RUNOFF AND RATE OF FLOW
- Soil types and roughness
- Storm intensity
- Contributing area
- Steepness of the terrain
- Length of the slopes
- Vegetation cover
- Storm duration
HOW OFTEN WATER QUALITY SAMPLING SHOULD TAKE?
Every conducted inspection
WHERE TO TAKE WATER QUALITY SAMPLING?
- Upstream
- Site outlet
- Downstream
WHAT TO SAMPLING DURING WATER QUALITY SAMPLING?
1.Nephelometric Turbiduty Units (NTU)–Instantaneous result using portable equipment.
2. Total Suspended Solid (TSS)–Must be analysed in lab
WHAT IS BEST MANAGEMENT PRACTICE (BMP)?
Measure, Practise, or Device that can:
1. Minimize erosion
2. Minimize the release of sediments from construction sites.
ABOUT BMP
- Don’t always consider local site need when selecting BMP
- Know limitations
- Unlimited types and number
- Drainage area
- Soil type and sediment size
Quality of good inspector
- An unbiased entity
- Knowledgeable
- Appropriate ESC training and experience.
- Consistent and proactive.
Motto of CISEC
Observe, inspect and report on what you found. Avoid mandating your requirements (unless you are qualify)
Ultimate goal for CISEC inspector
Work with contractor to reduce the amount of pollutant leaving construction site to a maximum practical extent possible.
What is two component of ESC plan?
- ESC Plan Report
- ESC Plan Drawing
“MORE” Effective ESC Plan
- Multi barrier approach
- On-going process
- Regular Inspection, Monitoring and Maintenance.
- Education and training
Inspector responsibilities during construction activities.
- Review ESC Plan to see if it current.
- Review BMP on site if it functional
- Documents findings
-Document your finding and communicate it to conractor.
-Don’t be confrontational to contractor - Ensure that BMP is effective during storm events
- Do not redesign ESC report and ESC plan drawing
-Inspector are not responsible if BMP are not working properly
-Inspector are not responsible to fix BMP that need to be fix - Be prepare to inspect during shutdown conditions.
- Be prepare to require temporary suspension of construction activities.
PURPOSE OF INSPECTION-To create snapshot in time
- Assess BMP on site whether they are effective and understans their limitations.
- Ensure ESC Plan are being implemented.
- Observe what is happening on site
- Determine if additional measure are being warranted.
- Accurately document site condition
- Maintain communication and work towards the ultimate goal of environmental protection.
INSPECTOR BASIC COMMUNICATION SKILL AT SITE
- Making observation
- Verbalize
- Write
- Listen
- Documentation
HOW TO HAVE A GOOD RELATIONSHIP WHEN WORKING WITH CONTRACTOR?
- Build a trusting relationship
- Realize that you are both the same team
- Show respect
- Don’t be bully
- Don’t assume you know his job
- Work together
