1 Introduction
Liepaja City Council, due to problems with the land owner of the land property"Mezbertuli" (early militarv base in Grobina) Mr. Janis Alens (represented by personauthorized by him - Mrs. G.Klints), has found an other solution. The new areaadjacent to the 'Mezbertulil has been offered as a site possible for a location of thenew landfill for solid household waste. Therefore City Council has asked theEnvironmental Impact Assessment Bureau to stop the evaluation of theEI.A reportwhile a new area will not be investigated.
At October 1, 1999 the EIA State Bureau has passed letter no. 1-09/160 (seeAppendix 1) to the Liepaja City Council, where had explained that the EIA report hasto be supplemented by following:
- drawings showing precise location of a new site,- location of potential access roads,- detailed description of geological and hydrogeological conditions of the
site,analysis of the site advantages and disadvantages in respect to theRegulations of the Cabinet of Ministers no. 38 from February 9, 1999"Solid Household Waste Landfills Installation, Management and ClosureRegulations", especially site correspondence to requirements stated inArticles 4 and 5.
This addendum to the EIA report deals with above mentioned problems. It has beencompiled in October, 1999.
2 General
A new site is located eastern from the early investigated area '¶Mezbertuli" (see Fig.1). In fact, the newA site was recognized as a possible location of a new landfill also inframes of the ELA report. Therefore area is already evaluated from the biologicaldiversity, landscape and other viewpoints, although drilling of bore holes anddetermination of groundwater table were not provided for this particular area.
Grobina parish Council has made decision no. 10 (from September 16, 1999) "Onland hand over for construction of regional waste landfill" (see Appendix 2) aftercompletion of the EIA report. Respectively, 27.1 hectare belonging to municipalityhas been offered as site possible for a new landfill location. Almost simultaneouslyagreement between the Grobina parish Council (September 29, 1999) and Mr. TalisBergmanis, owner of the farm "Vilteri", has been signed, because "Vilteri" is locatedin distance less than 500 m from the edge of the site offered for a new landfill (seeAppendix 3).
Owner of the "Vilteri" does not object that a new landfill will be located in distanceless than 500 m from his house.

3 Methods of the Work
Supplementary investigations included:- drilling of 5 bore holes (see Appendix 4),- detemiination of absolute heights of bore holes (see Appendix 5).- measurements of groundwater table (see Appendix 5).
Measurements of surface water EC have been provided, and this addendum to theElAreport has been compiled.
4 Geological structure and hydrogeological conditions
The total thickness of the Quaternary sediments is 10-15 m atGrobina site, and at themore than 50% of the cross-section consists of till. Only four types of Quatemarysediments have been found ( see Figure 2):
- technogenic deposits (thQ4), which at the landfill '"oligons" achieve 2-4m, comprising a waste layer of household/ commercial waste,
- alluvial deposits (aQ4) consisting mainly of sand. Sediments have a verylimited distribution and their thickness does not exceed 1.5 m,
- lacustrine deposits of the Latvian Formation (gQ31tv) are located all overthe area adjoining the landfill '?oligons", and consist mainly of sand andsilty sand. Maximum thickness of deposits reaches 4.7 m. Those depositsare found also within the till where their thickness achieves 0.5 m (borehole GS),
glacigene deposits (gQ3ltv) of the Latvian. The formation is developed allover the area and consists of loam or sandy loam with admixture of graveland pebble. The thickness is 7-12 m. Interbeddings of sandy material ( upto 0.5 m) might be found within the till.
5 new bore holes were drilled in order to determine geological conditions at the newsite. It was found, that geological cross - section consists of sandy loam, and itsthickness exceeds 3.5 m (see Figure 3).
Groundwater table lies on depth 1.3 - 1.8 m below the ground surface. Thegroundwater flow is directed towards the ditch which is directed towardsthe Alandariver, i.e. in south-eastern direction.
In fact, number of puddles have been found on top of the till, although sediments weredry in depth 15-20 cm.
Bcggy and lake deposits have limited distribution in nearest surroundings (see Figure2) and characterized in Table 1.

5 Surface water and groundwater quality
Measurements of EC (see Table 2) carried out in October, 1999 show that surfacewaiter is not polluted, and EC varies in range 304 - 668 4S/cm .

Groundwater contamination during EIA study has been found around the existingdurnp site "Poligins". It has rather limited distribution (about 0.6 hectares), and thefollowing parameters characterize the contamination level (well no. 5): COD - 200mgO2 /1, NH4 - 2.5 mg/l, although values of TDS and chlorides are low - only 390mg/l and 22mg/l (natural background values)
6 Possible Access Road
Seems, that the most suitable location of the access road is can be between theLiepaja- Riga highway and offered site, especially taking into consideration that the owner of"Mazbertuli" will not agree with a location of the access road through his landproperty (direction from Liepaja - Ventspils highway side).
Length of the access road will be about 2.5 km, and it will go along following firnmsor will pass their lands:
- "Apogi",
- "Vilteri".
The length of access road, in comparison with early offered site, practically will notincrease, but there is one advantage - it will be not necessary to cross the northernpart of Grobina Town. Hereto, the highway Liepaja - Riga anyway will be used bywaste transporting vehicles.
7 Conformity of the new site to requirements of the Regulationsno. 38 of February 9, 1999
The new site, likely as early selected, responds to requirements stated in Regulationsno 38 "Household landfill installation, management and closure regulations", whichhave been adopted by the Cabinet of Ministers in February 9, 1999.
Nevertheless, there is one problem - the farm 'Vilteri" is located in distance only 400- 450 m from the eastern edge of area supposed to be used for a new landfill. Thisproblem is solved due to efforts of Grobina pagasts Council, i.e. the Council andfarm's owner have signed agreement that the last does not have objections in case if anew landfill will be located closer than 500 m from his house (see Appendix 3).
8 Comparison of the new and early selected sites
Both sites - the new one and early investigated (westem from the new site) can beutilized for a new landfill location.
Envirom-nent conditions (geological structure,hydrogeological conditions, hydrologicconditions, biological diversity, etc.) are almost analogous for both sites. Also lengthof the access road has to be constructed and areas suitability for construction worksare very similar. Therefore, taking into consideration problems with land owner at"Mazbertuli". the new site looks better because the land owner is Grobina pagasts.Therefore, the new area described in this addendum can be recommended for a newlandfill location.

With respect to project time schedule, realised scope of work and comparable shortdistance to new location of potential waste disposal site State Bureau of EIA doesn'tconsider that full scale repetitive ETA procedure has to be executed.In order to finalise statement on Final report on Liepaja region waste disposal siteenvironmental impact assessment State Bureau of EIA. taking into account moreaccurate information, cQnsiders that project initiator or consultant companies have tosupplement the submitted Final report. This report has to be supplemented with:drawings of new-susgested area on maps. description of potential access roads,cornparison of advantages and drawbacks (sirmilar with already assessed territories).geological and hydrogeological characterisation of site. Also accordance with articles4 and 5 of Re-ulation No38 of the Cabinet of Ministers On construction. operationancl closure of sanitary landfills has to be checked and all needed additions have to becdone in relevant chapters and in summary of Final report.
In the same time population of Grobina pagasts has to be informed about new-selected site. We kindly ask to provide State bureau of EIA with a copy ofadvertisement. which will be published. Thus State Bureau of EIA interruptspreparation of statement on Final report until above mentioned additions will besubmitted to the Bureau. We kindly ask by submictingu to make clear or area of offeredsite Muzbertuli needs detailed assessment.
