Environmental Management System (ISO 14001)
On 15 March 2007, we obtained Environmental Management System Certificate according to ISO 14001 standard, after successful verification conducted by Crocert certification institution.
As part of Environmental Management System, certain aspects of environment have been specified by defining activities in the main and supporting processes and determining their environment aspects, namely organization activity components, our products and services which are or can interact with the environment. As part of the investment work processes and procedures of preparation for road service facilities (RSF) construction, our contractors’ and subconcessionaires’ activities in the motorway corridor are included, considering the fact that their actions directly influence our environmental management and the image of the company. More than 250 activities and 40 environment aspects are defined.
Analyzing important aspects of environment, legal acts and other regulations, technological and financial possibilities relevant objectives are set which are leading to decrease or elimination of adverse effects to environment. General and individual goals are determining environmental policy, and through the implementation of given programmes, the realization of set objectives is enabled. Harmful effects on the environment are hindered and pollution prevention is ensured by well defined objectives.
General, long-term and permanent environmental management goals are:
- Harmonization with all laws, implementation regulations and standards;
- Reduction of resource consumption to possible minimum;
- Reduction in producing waste and air pollution, water and soil pollution;
- Ensuring safe and environmentally friendly waste management;
- Raise employees awareness on necessity of environmental protection;
- Adopting new technologies and materials, when possible, which enable the realization of set goals.
The motorway, as well as all other types of traffic infrastructure such as railroad, waterways etc., significantly influence the animals’ habitat and the animals. Barrier effects appear in the area where animals because of road structure, barriers or traffic cannot cross the road simply.
Major negative effects of the roads are the following:
- direct loss of habitat, their fragmentation and fragmentation of population,
- habitat quality degradation, immediate peril of animals in an attempt of crossing the road, and the risk of endangering road users (crash with a big animal).
Fragmentation of habitat is recognized as one of the most important causes of reducing biodiversity in Europe. In the last ten years in Croatia, numerous kilometres of new motorways have been built linking the inland with the northern and southern coastal area, passing through the area of Gorski kotar, Lika and Dalmatia, going across the habitats of big and all other animals.
Motorway network Karlovac–Rijeka and Bosiljevo–Split divide the habitat of big animals into four parts. Although these roads influence the quality of the habitat and animals' possibility of movement, due to many structures and their length on the motorway, theoretically adequate motorway permeability for animals was insured. As much as 25% of the total length of Rijeka - Zagreb Motorway from Bosiljevo to Rijeka consists of structures that form potential crossings (bridge, tunnel, viaduct etc.) and one wildlife crossing structure, the Dedin Bridge. By telemetric monitoring of three kinds of beasts (lynx, wolf and bear) in the area of Gorski kotar it was established that each animal crosses the motorway, and that some of them have their habitats on both sides of the motorway.
Monitoring so far with the aid of sand trails and infrared sensors it has been established that all big mammals living in the area have been using Dedin wildlife overpass in Gorski kotar.
Although current findings impose that newly built motorways in Croatia influence the spatial reallocation of wolf packs, additional monitoring is necessary (telemetry, infrared sensors, tracking the animals which got hurt on the road, adequacy evaluation of all structures and their permeability) in order to establish the causes of movement and use of habitats in new circumstances (existence of motorway and crossings), potential critical points of crossing where animals get hurt.
At the same time, by ensuring maximum crossing opportunities vertically to the motorway stretch, by constructing the crossings and maintaining the crossings under the bridges, viaducts and over the tunnels, prevention of crossing the motorway by building adequate barriers is maximal.
Waste in Autocesta Rijeka - Zagreb d.d. is a result of company's work process and motorway users’ activity. Handling waste includes: managing waste, its temporary storage until handed over to legal entities authorized for waste collection and further waste treatment, regular maintenance and cleaning of roads and other surfaces, as well as structures in waste waters and precipitation drainage system, organization and keeping of prescribed records and documentation, and internal control over implementation of measures defined by the Waste Management Plan.
Hazardous waste that is a result of the Company's activity refers to: motor oils, oily water and sediment, and other types of hazardous substances from separators in waste waters and precipitation drainage system, oil filters, antifreeze, storage batteries, batteries, paints and varnish, thinning agents, oily cloths, packaging of motor and other oils, chemicals, toners, electric and electronic waste etc.
Harmless waste which is a result of the Company's activity appears in form of municipal waste, packaging, construction waste and old tires, under the condition that mentioned types of waste fully or partly do not have some of the characteristics of hazardous waste.
Inert waste generally refers to harmless waste which is not subject to significant physical, chemical or biological changes. It is not meltable, flammable, or in any other way reactive or biodegradable, and in ARZ's work activity it appears in form of construction waste, which refers to stone, soil material in all forms of its application, bricks, asphalt mixture and concrete.
Managing waste produced during motorway construction, realization of investment works, periodic maintenance and construction of service facilities, is conducted in accordance with the law and Environmental Management System documents. From 2007, trough Environmental Management System procedures, Environmental Management Plan and Contractor's Environment Protection Plan we are monitoring environmental protection measures taken by contractor, among other things they refer to municipal waste treatment and disposal, keeping waste oil treatment and its disposal, and keeping required records about waste on construction site, about waste transport from the site and delivering data to competent authorities.
Significant factor of environment impact reduction is by all means monitoring environment condition, and this is achieved through work supervision in order to evaluate whether prescribed measures for environment impact reduction are implemented, are they efficient or is it necessary to prescribe additional measures. Although the programme of monitoring environment condition is not specified in analyzed studies and location permits, existing legal regulations regulate this issue well.
All environmental protection measures are followed and implemented by ARZ, the subconcessionaires and the contractors during motorway construction and operation together with health protection and safety measures (prevention of accidents etc.). Daily inspection is carried out - supervision of all works and repairs, in order to ensure implementation of measures relating to environmental protection throughout contract duration. Environment Manager along with environmental associates from Integrated Management System shall, when necessary (once a year at least), conduct EMP audits in order to ensure that it is updated and corresponds to on-site situation; that discrepancies and corrective actions are duly documented in order to review implementation status and evaluate corrective actions.
Taking into consideration all specific qualities of the area through which the motorway from Zagreb to Rijeka passes, all necessary environmental protection elements were integrated into the project of construction of full profile motorway defined by the conditions of competent institutions and departments specified in location permits.
