CHAPTER 1. INTRODUCTION

The International Bank for Reconstruction and Development (IBRD) offered a loan to the Republic of Croatia for financing of the improvement of sewerage systems and wastewater treatment for settlements along the Adriatic coast and islands, i.e. financial support for the realization of the Program called the Costal Cities Water Pollution Control Project.

The Program is of a regional character and shall be realized on the coastal area with a high potential for tourism, important for the economic development of the Republic of Croatia, and it is planned to be realized on the principle of active participation of local authorities in cooperation with competent government agencies.

The International Bank for Reconstruction and Development (IBRD) and the Government of the Republic of Croatia have concluded a Loan Agreement (Loan no. APL 7226 HR) on July 2, 2004, in Zadar.

The Project Agreement was signed in Zadar on the same day between the International Bank for Reconstruction and Development (IBRD) and Hrvatske vode, by which Hrvatske vode have taken over the obligation towards the International Bank for Reconstruction and Development for the implementation of the Project.

The Program shall be carried out by Hrvatske vode PIU, named Hrvatske vode Jadranski project.

Implementation of the Program is planned in three stages, and the first stage of the Program shall be implemented in the period of four years (from 2005 to 2008). The total estimated cost of realization of the Program is ca € 280 million, and the value of the first stage is ca € 80 million. Value of the second stage is planed in ca € 120 million.

The primary objectives of the Program are protection of seawater quality, creating conditions for a safe economic development in accordance with the objectives of environmental protection and protection and improvement of the achieved level of environmental protection.

The basic developmental objective of the Program is to improve the quality of coastal water in the Croatian Adriatic and meet EU standards regarding the quality of environment in local communities.

Consistent with the scope and objectives identified above, the Program has three components: 0. Coastal Environmental Infrastructure component 1. Institutional Strengthening and Program Management Component to finance equipment,

technical assistance 2. Strengthening of the Coastal Waters Monitoring Network to finance equipment, civil

works and technical assistance

The key elements of the first and second phase of the Program are:

) Expansion of the sewerage network, adequate treatment and disposal of sanitary wastewater;

) Improvement of operation and management in municipal water and sewerage companies;

) Reform of financial and control instruments for wastewater disposal infrastructure.



4

Eleven subprojects are realized in first phase of implementation of the Program on the coastal area, The subprojects proposed for financing in Phase II of implementation of the Program are related to the 35 cities on the coastal area.

The World Bank appraises each project proposed for financing on the basis of social procedures and environment protection procedures, so-called ˝Safeguard Policies˝.

Contents of the Environmental Impacts Studies are defined considering Safeguard Policies of the Coastal Cities Water Pollution Control Project, by Ordinance on Environment Impact Assessment (Uredba o procjeni uljecaja zahvata na okoliš, NN 64/08), Operation manual – Environmental Framework and the corresponding feature of World Bank procedures.

Environmental Assessment has to be done in combination with EMP. According to the general definition, EMP may be described as a set of measures for elimination, avoiding or reducing adverse environmental and social impact of certain interventions in environment during construction, operation or removal. Interventions in environment are permanent or temporary human activities that may disturb ecologic stability or biodiversity, or cause any other adverse impact. This plan should define certain activities in order to implement preventive and protective measures, and to establish the system of monitoring of environmentally relevant parameters.

THE PROJECT

In connection with the Vodice-Srima-Tribunj sewerage system and waste water treatment plant, the following procedures were followed, in accordance with the Croatian law:

• Preparing of the Environmental Impact Study, according to Croatian regulations, • Procedure of acceptance of the Study – including public hearing • Issuing of corresponding decisions or permits of the Ministry of Environmental Protection,

Physical Planning and Construction

In accordance with environmental legislation, there is an obligation of assessment of environmental impact for interventions defined by the Ordinance on Assessment of Environmental Impact (OG No 64/08). The scientific basis for assessment of environmental impact is the Environmental Impact Study, which has to be worked out for eight types of interventions into the environment: construction of facilities for transport, power, water supply, industry, sports, waste water treatment, structural complexes (commercial centers), and mining.

The study of environmental impact of the sewerage system and waste water treatment in Vodice was made and issued in 2004. The procedure of study acceptance was conducted in accordance with Croatian regulations.

Also, in 2007, the Executive Summary had been prepared by Institut građevinarstva Hrvatske dd, Poslovni centar Split, according to Procedure C (see Operation Manual – Vol. III - Safeguard Policies).

This Environment Management Plan has been worked out in accordance with environmental policies of the World Bank, the document Operation Manual – Volume III – Safeguards Policies of the Coastal Cities Control Pollution Project, and with the legislation of the Republic of Croatia, and it completes the documentation related to assessment of environmental impact of the sewerage and waste water treatment system in Vodice.

Following the reviewing of the existing documentation by the World Bank, it has been agreed that Hrvatske vode will prepare the EMP according to the Bank’s procedures.

CHAPTER 2. PROJECT DESCRIPTION, OBJECTIVES AND ENV IRONMENTAL IMPACT 2.1. Project description and objectives

Construction of the public separate-type sewerage system is planned in the area Srima - Vodice - Tribunj. Trunk sewer, extending along the coast, will collect wastewater by gravity and transport it to the local pumping stations where wastewater will be pumped to the wastewater treatment plant in the area of Mrzanac. Treated effluent will be discharged from the wastewater treatment plant via long submarine outfall that will be situated southwest of the straight between Lukovnik and Logorun islands into the Kaprijski channel.

Basic sewerage network comprises eight local pumping stations with the appurtenant rising mains (3,2 km total length) and gravity main sewers (6,5 km total length). Apart from main sewers, secondary network will also be constructed. About 35.000 p.e. will be connected to the system; thus primary treatment is required for effluent discharged into the Kaprijski channel (less sensitive area). Necessary space shall also be reserved at the WWTP site for potential extension to the secondary treatment.

The Šibenik-Knin County Council has adopted the project concept elaborated in the study „Water Protection Study in the Šibenik-Knin County“ (Hidroprojekt-ING, 2000), based on the Preliminary design (Hidroprojekt-ing, 1997.g.) for the area Srima - Vodice - Tribunj, with the planned separate-type common public sewerage system. Central wastewater treatment plant is planned in the Mrzanac area. Submarine outfall with the diffuser will be situated southwest of the strait between the islands Lukovnik and Logorun into the Kaprijski channel.

1.1. Input data and facility sizing

Wastewater quantities and characteristics

Planned number of public sewerage system users at the end of the design period: Summer Winter Population 8.850 PE 8.850 PE Hotel guests 8.750 PE 4.000 PE Tourists in private and 17.750 PE 3.000 PE other accommodation Total 35.350 PE 15.850 PE

Wastewater quantities have been estimated at 80% of daily consumption; thus average daily wastewater quantity shall be Q = 3.650 m3/day and Q = 8.120 m3/day in winter and summer, respectively.

Wastewater load estimated based on ATV 131 guidelines.

Table: Wastewater load Indicator Winter Summer BOD-5 (mg O2/l) 260 263 COD (mg O2/l) 521 525 SS (mg/l) 304 306 Nuk (mg N/l) 48 48 Puk (mg P/l) 11 11

In the area of interest, apart from population and tourist, Oil Mill – Tribunj is another source of pollution. According to the Water permit, Oil Mill - Tribunj is obliged to treat wastewater before discharge into the public sewerage system, all in compliance with the Regulations on Limit Values of Parameters, Dangerous and Other Substances in Wastewater (OG No. 40/99, 6/01).

Sizing of sewerage system components

Mains can be divided to gravity mains and rising mains. Gravity mains:

• ø 300 mm 2,0 km • ø 400 mm 1,0 km • ø 500 mm 2,5 km • ø 600 mm 1,0 km

Rising mains: • ø 300 mm 1,9 km • ø 400 mm 0,6 km • ø 500 mm 0,7 km

There are 8 pumping stations, situated at the trunk sewer alignment along the coast.

Wastewater treatment plant Required area for WWTP construction phase I. (primary treatment) is 0,20 hectares. Area for primary (I) and secondary (II) treatment is estimated at 0,50 ha. Rectangular area of 50 x 100 m should be foreseen.

Two treatment lines are foreseen. Primary treatment will comprise the following. • floating matter removal • suspended solids reduction • reduction of oils i.e. organic matter portion.

Basic components of primary (I) treatment WWTP are the following: • automatic coarse screens, • automatic fine screen, • grit-grease removal

The following components shall be added to expand the WWTP to secondary (II) treatment (optional):

• biological tank • secondary settling tank • sludge thickener • mechanical sludge dewatering

Submarine outfall Submarine outfall with the diffuser is planned, in the length of 1900m. In fact, the waste waters planned to be discharged into the sea will first be treated to a certain treatment stage and only then discharged in a carefully selected location.

One of the objectives in the waste water discharge is to endeavor to make the discharge to the water column under the pycnocline.



8

If this objective can be achieved, then the probability of waste waters reaching the sea surface will be small. It has been found out, however, that during summer cyclonic changes the complete homogenization of water column can take place in the southern shallower parts of the Channel. In such conditions, waste waters could come up to the sea surface and be taken by wind-driven surface currents to the nearby shore in a relatively short period of time.

The outlet location, the conditions of waste water discharge and the treatment stage have been determined taking into account the following:

a) The area to be protected by applying the existing standards for the sea quality. b) The outlet end must be located in a predetermined area. c) The initial dilution requiring the outlet opening to be as far as possible from the

protected area. d) The use of the diffuser enabling to increase initial dilution, i.e. with the openings

of Ø 10-15 cm. e) The dilution at the boundary of the 250-300 m wide sea body of minimum

100.000 with the initial dilution, the secondary dilution (circulations) and bacteria decay (T90 of 2,5 h).

f) The circulation velocity toward the shore of 10 cm/s. g) The flow rate in the outlet to be about 1 m/s, and in the diffuser 2 m/s.

2.3. Environmental impact 2.3.1. Particular importance of discharging of trea ted water into see – Kaprijski Channel

Water protection is implemented by prescribing the quality of water defined in regulations referring to: - the water recipient, - discharged wastewaters.

Regulations referring to the water recipient govern the purpose and method of water usage (National Water Protection Plan NN 8/99 and Regulation on Classification of Waters NN 77/98). Criteria for maximum allowed concentrations of wastewater are determined based on scientific researches, as well as laboratory and «in situ» monitoring of indirect and direct impact of hazardous and toxic substances on human organism.

Allowed concentrations have been selected so as not to disturb the natural representation of species of organisms and their development stages, at the same time enabling the preservation of all existing natural characteristics of water courses and the sea.

Regulations referring to discharged wastewaters:

- Regulations on Boundary Values of Parameters of Hazardous and Other Substances in Wastewaters (NN 40/99) determine the allowed concentrations of individual toxic and hazardous substances in wastewater after the treatment process of such waters.

- Regulations on Modifications and Amendments of Regulations on Boundary Values of Parameters of Hazardous and Other Substances in Wastewaters (NN 06/01) refers to wastewater discharge into the sea and, among amendments, in Article 3 the document expands Article 4, Paragraph 1 for Items e) and f), as follows:

e) the sea, with wastewater discharge via a marine outfall into «less sensitive areas» (an area with good exchange of water mass not susceptible to eutrophication or oxygen reduction or having low probability to become such due to wastewater discharge from public drainage systems),

SIZE OF PLANT TREATMENT DEGREE under 10.000 EP appropriate

10.000 to 50.000 EP First (I) over 50.000 EP first (I) + second (II)

f) the sea, with wastewater discharge via a marine outfall into «sensitive areas» (an area with poor exchange of water mass susceptible to eutrophication or having high probability to become such due to wastewater discharge from public drainage systems),

SIZE OF PLANT TREATMENT DEGREE under 10.000 EP first (I)

10.000 to 50.000 EP first (I) + second (II) over 50.000 EP first (I) + second (II) + third (III)

⇒ in case the sensitivity of the Kaprijski Channel changes (increases).



10

The above Regulations determine the treatment degree for the WWTP Vodice – First degree Wastewater Treatment Plant since the Kaprijski Channel is a «less sensitive area».

The application of these Regulations ensures the monitoring of the discharge of waste substances by each individual contaminator, as well as the control of operation of the wastewater treatment plant.

Both previously described aspects of water protection are interrelated, i.e. the concentration of waste substances in wastewater prior to the discharge into the recipient shall directly impact the concentration of pollutants in the recipient. Consequently, efficient implementation of water protection requires the control of the allowed concentration of pollutants in wastewater, enhanced by the control of maximum allowed values of hazardous and toxic substances in the water recipient.

These Regulations and Decrees define the requirements on the allowed concentration of hazardous and toxic substances in discharged wastewaters and the water recipient, i.e. their application represents only the basis of an integral program of control and preservation (or upgrading) of the quality of the coastal sea with the final goal to ensure and upgrade the natural environment in which we live.

The required wastewater treatment degree at the Vodice-Srima-Tribunj Riviera - Wastewater Tr eatment Plant Vodice According to the sensitivity of the recipient (the Vrgada Channel sea) and the size of the plant for individual phases of construction, and the National Water Protection Plan (NN 8/99), the required treatment degree is: PHASE I (N = 22.000 PE) For: Plant size of 10.000÷50.000 EP Recipient category: «less sensitive sea»

Treatment degree: First (I) treatment degree with the provision of a marine outfall

In the next development phase of the BIOGRAD n/r “KUMENAT” WTP, at this location the following shall be constructed: PHASE II (N = 44.000 EP) For: Plant size of < 50.000 EP Recipient category: «less sensitive sea» Treatment degree:

First (I) treatment degree with the provision of a marine outfall

The boundary values of parameters of wastewater discharged into a natural recipient from a wastewater treatment plant after a given treatment degree are specified by the Regulations on Boundary Values of Parameters of Hazardous and Other Substances in Wastewaters (NN 40/99) and the Regulations on the Modifications and Amendments of the Regulations on the Boundary Values of Parameters of Hazardous and Other Substances in Wastewaters (NN 06/01), as follows:

Submarine outlet The use of the long submarine outfall with an adequate treatment level is rational, having in view the proved self-cleaning capacity of the sea as a recipient, i.e. its power to reduce the bacteriological pollution that is difficult to eliminate by various technical and technological processes. The natural properties of the sea water offer the possibility for the sea as a recipient to participate, under certain discharge conditions, in further degradation of organic matters without any danger for the ecological stability of the marine environment at the discharge site. That is noticeable especially with smaller drainage systems.

To design the submarine outfall and to define its exact position, it is necessary first to make a hydrographic study containing all data on the sea bottom geology, prevailing winds and local currents at the foreseen location. Based on the data from the hydrographic study, and taking into account the sea water categorization in the zone of effluent impact and in the area outside the circle with a radius of 300 m around the outfall diffusors (the National Water Protection Plan requires the sea water outside the radius of 300 m around the outfall difussors to be of category II) as well as the forbidden zone of 300 m from the coast-line for sports and recreation, the exact length and position of the submarine outfalls and their related diffusors will be determined.

A diffuser is recommended in order to achieve required dilution even for small settlements. Guidelines for diffuser design are given hereinafter (UNEP, 1995): - diameter of diffuser orifices shall not be under 10 to 15 cm, - recommended distance between diffuser orifices shall be equal to one forth of the sea

depth - discharge velocity from diffuser orifices shall be about 2 m/s.

Wastewater treatment plant of the planned 44.000 PE (22.000 PE – Phase I) capacity and ”first degree” will be constructed, complete with the submarine outfall for effluent discharge into „less sensitive area“.

In compliance with the adopted wastewater quantities, Conceptual Design foresees construction of submarine outfall of about 1.900 m total length. Assumed diameter of HDPE pipes will be Ø 500 mm.

Submarine outfall direction and length have been defined in the Hydrographic Study “The results of research works at the submarine outfall alignment of the Vodice-Srima-Tribunj public sewerage system” («Rezultati istraživačkih radova trase podmorskog ispusta otpadnih voda sustava javne odvodnje naselja Primošten») HHI, August, 2003.

2. Oceanographic data

Figure 2. Map of Oceanographic measurements (OC) and See currents measurements (ASS) in the area of the submarine outfall

Oceanographic measurements carried out to determine oceanographic characteristics of the marine environment of Srima - Tribunj – Vodice sewerage system outfall comprised measurements of sea currents at two gauging stations, measurements of vertical profiles of temperature, salinity and density at 10 stations as well as seawater sampling at 3 stations, in order to determine nutrient concentrations, pH-values and dissolved oxygen (% of saturation). The study also analyzed the data on sea levels registered at the Zadar-Gaženica mareographic station, which is being representative for the researched area, the data on visual observation from ships (database of HHI - Croatian Hydrographic Institute) as well as measurements of surface waves generated by wind in the broader marine environment of the outfall. Measurements were carried out in the period from September 11th 2001 to October 10th 2001. Thermohaline characteristics Vertical temperature profiles point to homogeneity to about 15 m depth. Developed thermocline has been observed in the layer between 15 and 23 m. At the stations situated east, thermocline is even more pronounced and starts at about 18 m depth. Under the thermocline, temperature gradually decreases to the seabed. Seawater temperature in the layer by the thermocline ranges between 19,5 and 19,7oC. Temperature is constant to the thermocline (which is situated between 15 and 23 m depth), then it decreases and ranges from 15,4 and 15,7oC close to the seabed. In the surface layer salinity ranges from 37,9 and 38,1‰ and increases towards the seabed to be about 38,4‰. Seawater density, which depends on the sea temperature, salinity and depth (pressure) has similar vertical distribution as seawater temperature, except near the surface where somewhat



14

smaller salinity causes lower density. Seawater density ranges between 1.027,1 and 1.027,2 kg/m3 in surface layer and about 1.028,5 kg/m3 in bottom layer. Sea currents In the broader area of Vodice, average daily oscillation of sea level (average amplitudes of the tides) is 26 cm. At the station ASS-1, maximum measured current velocities were 31 cm/s in the surface layer (3 m) and 19 cm/s in the bottom layer (46 m). Average current velocities were 5,5 cm/s (3 m) and 2,6 cm/s (46 m). The resulting direction of surface currents was NW , while S was the resulting direction of bottom currents. Stability factors in the surface and bottom layers were 21,7% and 35,4%, respectively, which points to great variability of sea current directions, in particular in surface layer. At the station ASS-2, maximum measured current velocities were 37 cm/s in the surface layer (3 m) and 13 cm/s in the bottom layer (58 m). Average current velocities were 9,1 cm/s (3 m) and 2,3 cm/s (58 m). The resulting direction of surface currents was NW, while WSW was the resulting direction of bottom currents. Stability factor in the surface layer is relatively high (59,8%), and lower in the bottom layer (38,1%). It points to relatively stable sea current direction in surface layer and less stable one in bottom layer. As can be concluded from the current rose, about 23% of the surface current field and about 8% of the bottom current field were directed onshore. In fall-winter period of the year (November-March), the most frequent are the waves generated from SE direction, with the usual heights from 0,5 to 1,5 m, although maximum wave height up to 3,5 m were recorded in the broader marine environment of the Srima - Tribunj - Vodice sewerage system outfall. Frequent are also waves generated from NE direction with the maximum height up to 2,5 m. Nutrient concentrations The highest nitrite concentrations were recorded at the station ASS-2 at 50 m depth (0,197 mmol/m3). Maximum nitrate concentrations (0,401 mmol/m3) were also registered at the same gauging station. The highest orthosilicone concentration (0,752 mmol/m3) was recorded at 50 m depth as well as the ammonia (0,706 mmol/m3) on the surface at the station ASS-1. The highest orthophosphate concentration (0,036 mmol/m3) has been registered at the surface of the station OC-1. The minimum dissolved oxygen (% of saturation) (90,76%) has been registered on the surface at the station OC-1. The maximum dissolved oxygen (% of saturation) (97,44%) has been registered at 20 m depth at the station ASS-1. Recorded pH values ranged from 8,25 to 8,27. Eutrophication level assessment Nutrient concentrations, dissolved oxygen (% of saturation) and pH-value, and their vertical distributions recorded at the stations OC-1, ASS-1 and ASS-2 were within the limit values recorded at open sea (Zore - Armanda, et al, 1991). Thus, it all points that there was no eutrophication caused by antropogeneous activities at the researched location.

2.3.3. Environmental impact and prevention measures Potential adverse environmental impacts may occur:

• during construction, • during system operation, • due to accidents and failure in operation.

0. Environmental impacts during construction Noise

During construction works, noise will be emitted by construction machinery, vehicles for transport of material and equipment, plants, manpower transport vehicles etc. Noise level can exceed allowable limits on and outside the construction site, permanently or periodically.

Air pollution

Airborne particles carried by wind as a consequence of dusting, caused by earth and other works at the construction site.

Loose material carried by wind from transport vehicles and exhaust gases from construction machinery.

Soil pollution

Disposal of surplus excavated earth material on surfaces not intended nor prepared as landfill. Oil and lubricant spill from construction machinery and vehicles. Washing and transport of loose material scattered over carriageway by precipitation.

Seawater pollution

Excavation of the outfall trench could cause seawater pollution by increased turbidity and transport of fine particles by sea currents and their settling outside the project impact area.

Impact on flora and fauna

During construction of facilities and installations, parts of the existing habitat will be damaged, which will adversely impact the organisms settling within the WWTP site.

Submarine works will destroy parts of benthos communities and disturb the nutrition of pelagic communities.

Impact on existing facilities

During construction, possible are damages to municipal utilities (water supply, power supply…).

Impact on traffic

During laying of sewerage system mains along and/or under the existing asphalt roads, traffic will be disturbed.



16

0. Impacts during system operation Flora and fauna

Flora and fauna of the existing terrestrial habitat will change. Some of green surfaces will be replaced by solid surfaces. Due to changes in habitat conditions, some species will desert the existing habitats.

Changes in benthos communities are possible in the diffuser vicinity.

Odors

Evaporation or vaporization of odorous gases and vapors (ammonia, amine, hydrogen sulfide, merkaptans, hydrocarbons, organic acids...) generated due to organic and inorganic matter degradation, is expected at the following sewerage system facilities: raw wastewater pumping stations, coarse screens, grit-grease removal, waste collection tanks.

Noise

High level noise can be generated at the following public sewerage system facilities: pumping station, blower unit

Decline in land value

Since wastewater treatment plant is situated far enough from the residential area, there should be no large scale decline in the adjacent land value. However, inadequate visual appearance of the facility as well as irregular maintenance would significantly impact the landscape.

Wastewater infiltration

Wastewater infiltration into soil and/or seawater can occur at the mains and tank joints due to cracking or hardstandings at solids load points.

Wastewater infiltration into the sea could occur at submarine outfall cracks i.e. pipeline damages.

Insect breeding

Insect breeding is possible in warm periods of the year at still waters, tanks, wastewater puddles and plashes, work areas or green areas.

Impact on the use of coast

Sea pollution could impact the coast, thus making it unsuitable for planned use (recreation, sports) including residential and hotel development.

Impact on the sea use

Coastal sea could be polluted and therefore unsuitable for bathing, water sports. Human health could also be endangered.



17

Impacts due to waste disposal

Disposal of wastes produced at the wastewater treatment plant could cause unwanted environmental impacts such as odors and insect breeding, and could also endanger life of people and animals

0. Environmental accident impacts

Force majeure (major earthquake, ravages of war) could cause damages to public sewerage system facilities. It would result in uncontrolled release of untreated wastewater into coastal sea thus deteriorating seawater quality to the present state or even more polluted. Due to “outage” of system facilities, there could be a decrease in system operation efficiency and thus short-term increase in coastal sea pollution. Submarine outfall damages are also possible resulting in uncontrolled wastewater spill in unwanted locations. If submarine outfall is to be constructed of high-density polyethylene (HDPE) pipes, occasional pipeline lifting from seabed and floating is possible. In respect to materials and construction technology, small-scale fires can be generated due to break in power lines or electrical machines. Gases released from wastewater surfaces can corrode unprotected metal parts, thus causing disturbances in operation and environmental accident.

Law on Physical Development and Construction - Zakon o prostornom planiranju i gradnji, NN 76/07, in the part regulating site organization (Articles 252 through 254), requires the following mandatory measures:

- the site shall be delimited to prevent uncontrolled access,

- the site shall be marked by the sign plate containing the name or firm of the investor, the designer, the contractor and the supervising engineer, name and type of the structure, the name of the agency that has issued the construction permit, classification code, registration number, date of issuing and expiration of the construction permit, as well as the note on cultural property, if the structure is entered in the Register of Cultural Property of the Republic of Croatia,

- parts of the site extending over larger areas (e.g. roads, railways, ducts, etc.) shall be fenced, or marked by special signs,

- in case of temporary occupation of public roads for the purpose of construction, the investor or the contractor shall obtain the corresponding permits from relevant agencies; preliminary works may be carried out on surrounding land only if the investor has obtained the permission from the land owner for carrying out of such preliminary works,

- temporary structures erected for the purposes of the site, equipment, unused material and waste shall be removed from the site, and the site shall be returned to previous condition,

- on site, necessary measures shall be taken and implemented for protection of air from pollution, protection from noise, soil and ground water protection, safety at work, and protection of public health.

Taking into consideration the above remarks, it may be assumed that in the construction phase of the facilities there will be some small and short environmental impacts. Such impacts are usual in interventions in municipal infrastructure, involving various field works. In this sense, the following forms of environmental impact may be foreseen during construction: - minor traffic problems, - increased air pollution by dust particles, - increased soil erosion and spreading on roads (during rainfall), - increased noise level, - additional production of waste material.

In connection with traffic problems, in addition to the safety aspect, one may expect increased local air pollution due to increased emission of exhaust gases of motor vehicles, as well as local pollution by noise.

During earthmoving works, in particular during the dry season, locally increased concentration of dust is probable. Construction machines (vehicles) can bring sediment (soil or sand) from site to roads. Sediment can also get to roads during rain.

The waste produced during construction mainly consists of construction waste and municipal waste, managed in accordance with the Waste Act, which, inter alia, implies separating of packing material from municipal waste, and regular transport of waste to the landfill.

During operation of the facilities, in proper handling conditions, no particular adverse environmental impacts are expected. Namely, during operation, waste (in the form of sediment or sludge) is produced only in the retention basin, but it is, together with waste water, forwarded towards the treatment plant, and in the treatment plant. There is a potential risk, in case of accidental damage of parts of the sewerage network, of infiltration of ground water into the sewerage network, or of exfiltration of waste water into the underground. However, as a prevention measure, the user of the facility must regularly check the impermeability of the sewerage network (in the frame of his regular annual control and maintenance plans) and, if necessary, repair the damaged parts.

Other, mainly minor environmental impacts, both at the treatment plant and in the sewerage network, are mainly related to improper operation and/or accidental events. The annexes, in table form, give the possible environmental impacts, including planned mitigation measures.

On a long term, however, positive effects of construction of project facilities may be expected, reflected in higher numbers of population connected to sanitary sewerage, thus preventing environment pollution, in particular pollution of ground water and see water.

As the Project will be implemented within already existing areas, any cultural issues are not foreseen, but the civil work contracts for all infrastructure investments will include requirements that the contractor is obliged to look for chance finds and stop the construction work and alert Ministry of Culture in case of chance finds.

The fundamental law regulating the problems of environmental protection in the Republic of Croatia is the Environmental Protection Act (OG 110/07). This law regulates the issues of environment protection, reduction of risks for human health and lives, ensuring and improvement of the quality of life for the benefit of present and future generations. The environment protection promotes overall conservation of the quality of the environment, conservation of natural communities, rational and environment-friendly use of natural sources and energy, as the basic precondition for healthy and sustainable development. The efficiency of national environmental control is supported by the Croatian Parliament and the Government of the Republic of Croatia, and by the representative and executive agencies of local administration, through issuing of environmental protection strategies and programs, and other documents relevant to environmental protection. Professional activities in environmental protection and enforcement of environmental protection measures are supported by national government agencies and agencies of local administration in charge of environment protection, as well as by legal entities registered for carrying out professional work on environment protection. Citizens, as individuals or organized in societies for environmental protection, professional associations and other non-governmental organizations, also contribute to achieving of the goals of environmental protection and implementation of efficient environmental protection. The local administration unit regulates, organizes, finances and promotes the environmental protection activities of regional or local importance. For the purpose of achieving of coordinated economic development in accordance with the requirements of environmental protection, and of the professional and scientific basis for regulation of certain issues, the Government establishes the Council for Environmental Protection (hereafter: the Council), consisting of scientists, professionals and public activists. The Council issues the opinions, proposals and evaluations on coordination of environmental issues and economic development, and on documents proposed by the Government and the Parliament. Legal entities registered for professional activities in environment protection carry out the tasks related to monitoring of the environment status, prepare basic data and environment protection studies, prepare and elaborate the environmental impact studies, and conduct professional training in environment protection activities. The environmental protection is based on respecting of the principles of international legislation on environmental protection, generally accepted principles, respecting of scientific knowledge and best worldwide practices. The documents regulating environmental protection in the Republic of Croatia are, as follows: - Strategy of environmental protection , defining and directing, on a long-term basis, the goals of environment management in accordance with the overall economic, social and cultural development of the country, issued by the Parliament on the proposal by the Government,



45

- Environmental protection programs for the territory of the County and the City of Zagreb,

containing the basic goals, conditions and criteria of environment protection in general, priority measures in components and spatial entities, and working out of the principles and guidelines of environmental protection contained in the Strategy. The environment protection program for the territory of a County or of the City of Zagreb is issued by the relevant County Assembly, or the Assembly of the City of Zagreb. The programs covering minor city or municipality areas are issued by the city or municipal council, when it is necessary to protect the environment in a specific city or municipal area to preserve cultural, historical, aesthetic and natural features of the landscape.

- Environment status reports are prepared every two years for the purpose of the Strategy

and the Programs, and other documents relevant for environment protection. Implementation of environmental protection is based on: - Environment quality standards , containing limit values for specific components of the

environment and for highly valuable, sensitive or endangered areas, defined by special regulations, if not already defined by the law.

- Environmental impact assessment, intended to provide application of the precaution

principle by adjusting and modifying of the planned project, construction, reconstruction or activity to the receiving capacity of the environment in the given area. The environmental impact assessment helps to perceive the possible adverse effects of the intended project on soil, water, air, forests, climate, human health, flora and fauna, landscape, cultural heritage, their mutual relations, taking into account other planned projects and possible interactions with existing and planned projects in the given project area. The Government defines, by its regulations, the projects that require the assessment of environmental impact, the contents, terms and methods of preparing of environmental impact studies, methods of assessment and reaching of conclusions on the intended project, ways of informing the public, and the terms and methods of public participation in decision-making, rights and duties of the parties in the process, etc. The impact of the project on the environment, its evaluation and its acceptability is assessed by the commission on the basis of the study of environmental impact. The solution giving or refusing approval of the intended project is issued by the National Authority for Environmental Protection.

- Physical plans that must include measures of protection of soil, water, air, forests, climate,

human health, flora and fauna, landscape, cultural heritage, waste management measures, noise protection and fire protection measures, and other measures for protection of the environment.

- Environment monitoring. In all projects where the assessment of environmental impact is

mandatory, the legal entities shall, through authorized firms, measure the emissions and keep the records, measure the emissions or participate in such measuring, proportional to their participation in environment pollution, and participate in monitoring of natural and other phenomena resulting from environment pollution.



46

- Inventories of environment pollution , kept by the County or City of Zagreb office in charge of environmental protection.

- Environment protection information system , established by the National Authority for

Environmental Protection, in cooperation with the ministries and national administration agencies.

- Environmental protection intervention plans, etc. Administrative control over implementation of the Environment Protection Act and regulations based on the Act is exercised by the National Authority for Environmental Protection. Implementation of enforcement of the Act, regulations and other individual acts, conditions and operating methods of legal entities, and of environment protection measures are inspected by the environment protection inspector and other inspectors within their respective capacities. The environment protection inspection may also be performed by another employee of the National Authority for Environmental Protection, if authorized by the Director. The inspection on the first level is carried out by the County office (or City of Zagreb office) in charge of environment protection, and on the second level, by the National Authority for Environmental Protection. Besides the above agencies, in the Republic of Croatia there are many professional institutions and non-governmental organizations dealing with environment protection. The list of legal entities authorized by the Ministry of Environmental Protection, Physical Planning and construction for professional activities in the field of environment protection is given on the Ministry web-site. Finally, besides the above fundamental law, the problems of environment protection are dealt with by a number of other laws and bye-laws, the most important of them being listed in this annex.
