Bulgaria - Municipal Infrastructure Development Project : environmental due diligence report (Vol. 4) : Bulgaria - Municipal Infrastructure Development Project : environmental framework (English)

The objective of the Municipal Infrastructure Development Project for Bulgaria is to improve the provision of water and wastewater supply by building various dams. Building of the dams will lead to an inevitable change of the thermal-physic properties of the bearing stratum and thence, of the microclimate. That change, however, affects only the dam area, and as a result may have a beneficial eject on the unaffected flora and fauna. The main pollution source of the dams is mines, especially during heavy rain, for which reason the design contains special measures for their diversion from the reservoir and beyond the water catchments area of the reservoir. Some other environmental concerns and mitigation measure are the following: 1) restrict land disturbance within the construction time limits; 2) use mobile water sprinkling systems for dust suppression, on the temporary roads across settlements and at the construction sites; 3) construct a water meter station in the dam lake tail for metering of water inflow; 4) sanitize the reservoir bed; 5) erect stationary chemical toilets during the construction and operation phases; and 6) ensure release of ecological discharge from an appropriate level of the lake (not exceeding 10 m).
