3. Sub-project impacts


5.1 Environmental impacts
This section assesses the environmental benefits resulting from reduction of pollutants concentration to the limits of the law. The indicators used are:
• Pollutant concentration below law limits in case of air and water pollutants.
• pH 7.16 6-9.5 6-9.5
• TSS, mg/l 955 800 700
• COD, mg/l 2080 1100 1000
• BOD5,mg/l 1380 600 550
•
• Percent load reduction in stack and effluent emissions
• 90-95%
• Percent reduction in workplace concentration
• 60-65%
• Solid and hazardous waste management complying with law.
• 30-35%


4. Self monitoring (SM) plan
• The parameters to be monitored. The pollutants depend on the type of industry and technology used.
• الاسال هيدروجينى 6- 9
• الاكسجين الحيوى 50 ملجرام/لتر
• الاكسجين الكيماوى 250 ملجرام/لتر
• فوسفور كلى 2 ملجرام/لتر
• زيوت وشحوم 10 ملجرام/لتر
• كمية المواد الصلبة العالقة 50 ملجرام/لتر
• معد لدرجة الحرارة اكثر من 3 درجات
• اجمالى البكتريا القولونية 400جرثومة/100ملليمتر
• The time when monitoring is performed. The processes should be operating when monitoring takes place.
• Daily/lab analysis
• The location of the monitoring should also be specified.
• Lab room beside the unit
• The equipment used to perform measurements should be specified
• Lab.equipments(spectrophotometer/codmeter/bodmeter/phmeter/bacterial meter/tds-conductivity-temp meter/dissolved oxygen meter
• Monitoring frequency should be specified. The PPSI project requires that the monitoring plan be repeated on quarterly basis for the first year of sub-project operation. However higher frequency could be found necessary.
• The monitoring ll be weekly and there are a monthly monitoring
• Equipment calibration plan should be included
• Water analysis monitoring equipment(spectrophotometer/ion selective electrodes)
• Oil/grase monitoring equipments
