1. A�er emptying, cleaning, and visual inspec�on, water is needed again to refill the separator systems for the general inspec�on. Should this be included in the inspec�on price – meaning delivery of water for refilling – or do we have hydrants on-site with which we can fill the systems?

We have hydrants where the contractor can get the water to fill up the separators a�er cleaning/emptying.

2. How much sludge can be expected in the stormwater reten�on basins? Is it solid or more liquid?

Although we have the dimensions of the stormwater reten�on basins, we cannot es�mate how much needs to be disposed of. Do you have some key data from previous instances?

We have historical data of previous emptying (please see atached Basin Disposal Informa�on March 27, 2024), usually it took our current contractor several days to clean the RRB. For the consistence (solid or liquid) I can’t really tell, since there are many factors involved: how long it has not been cleaned, how much rain there was before cleaning, how hot it is outside, so basically a lot of weatherly impact.

3. What wastewater flows into the pump sta�ons? Wastewater from the separators? Domes�c wastewater? Rainwater? Is a disposal company needed to access the pumps? Can the pumps be pulled out from the top for maintenance?

3.1- Q: What wastewater flows into the pump sta�ons? Wastewater from the separators? Domes�c wastewater? Rainwater?

A: it is Wastewater from the separators.

3.2- Q: Is a disposal company needed to access the pumps?

A: Yes, the contractor will have access the pumps.

3.3- Q: Can the pumps be pulled out from the top for maintenance?

A: Yes, it is possible to pull the pumps out from the top for maintenance.

4. Where does the wastewater from the separator systems need to be disposed of? This informa�on is on your disposal cer�ficate. This is important for the disposal company to properly calculate the landfill trip.

The wastewater needs to be disposed at a cer�fied disposal company.

5. What is in the external oil tanks? Is it an oil-water mixture? Used oil? Is wastewater pumped into these tanks?

The external oil-tanks shall be in another contract – M&R liquid storage tanks. I really don’t know why they were in this contract in the first place, currently they get maintained by our tanks contractor.

6. Is there any informa�on more regarding this separator KSS DRMO (YARD) NG 6?

Unfortunately, we don’t have mor informa�on for this POL. Due to the age of the Separator and the missing Type plate is the only informa�on we have the size NG6. (Please find Atachment Picture of KSS DRMO (YARD) NG 6) with addi�onal Pictures)
