MONITORING PROGRAM OBJECTIVES The Alaska.Power Authority (Power Authority) has proposed to construct the Susitna Hydroelectric Project, consisting of two large hydroelec- tric dams on the Susitna River in Alaska.. The initial estimates of future air pollutant emissions during the facility construction in- dicate that the emissions from the temporary diesel electric generators may be high enough to require submittal of a ~ermit to Construct with Prevention of Significant Deterioration (PSD) review to the Alaska Department of Environmental Conservation {ADEC). Section 18 AAC 50 .. 300(c)(l) of the Alaska Air Quality Control Regulations requires, as part of a PSD review, submittal of ambient air quality data for those pollutants which are present at the site in 11 Significant" background concentrations. ADEC has indicated that because the Susitna project site is located far from any industrial emission sources, total suspended particulates (TSP) caused by natural windblown dust is the only significant air con- taminant at the site (Alaska DEC, 1984). The pre-permit air quality monitoring at the site will, therefore, be designed solely to measure background TSP concentrations. Based on discussions between the Power Authority and ADEC and based on an onsite meeting on May 30, 1984 be- tween ADEC and Hat~za-Ebasco representatives, the objectives of the Susitna monitoring program are as follows: 0 0 5393A Measure background TSP concentrations at the site during the summer season; Take the measurements at two locations: at the river level where fugitive dust impacts during construction are expected, and on the plateau above the river where impacts are expected from point source emissions; I-1 .. . o Comply with all federal guidelines for quality assurance dur- ing the monitoring program. B. REGIONAL DESCRIPTION :. 1. Damsite Descriptions The proposed Susitna Hydroelectric Project consists of two dams located on the Susitna River in Alaska. The genera1 locations of tne two pro~ posed dams are shown in Figure 1. The proposed Watana Dam, 1 ocated near River Mile 184, will be an earth dnd rocicfill structure. The proposed Devil Canyon Dam, located near River Mile 152, will be a thin conc\"ete arch dam. The Devi 1 Canyon dam construction wi 11 coimlence about 10 years after the start of Watana dam construction. The Devil Canyon dam will require much less earthwork than the Watana dam. 2~ Climatological Description The Susitna project area generally experiences cold, dry winters and cool, wet summers. An onsite meteorological station nas Been operated at the Watana fie.ld camp since 1981. A summary of the monthly temper- ature and precipitation patterns at the Watana site is shown 1n Table 1. Based on two years of data, the monthly average temperatures range from -16.7°C in January to +ll.5°C in July. As shown in Table 1, the measured precipitation was very low during the winter months. Most of the 381 mm (15.0 inches) of measured annual precipitation has occurred as rainfall from May through September! However, the existing meteorol ogi ca 1 station may have had di ffi cul ty collecti119 light snowfall during periods of strong winds, which are corrmon during the winter. Therefore, it iS li'kely that the actual winter precipitation is higher than indicated in Table le Onsite per- sonnel hava indicated that snow generally accumulates on the ground be- tween early O~tober and mid-May. 5393A I-2 • ..

WATANA DAMSITE HI-VOL SAMPLER LOCATIONS Background.total suspended particulate (TSP) concentrations at the Wat- ana damsite will be measured at two locations: near the existing Wat- ana field campsite, and at the Susitna River. The two sampling loca- tions are shown in Figure 3. 1. Watana Campsite Samplers A set of two collocated hi-vols was established near the Watana camp- site on May 29, 1984. These samplers will measure baseline TSP concen- trations in the main plateau regions above the river. The configura- tion of the campsite hi-vols is shown in Figure 4. The samplers are located at coordinates Alaska State Plane, Zone 4~ N 3,232,764 and E 748,863, and at an elevation of 2,270 feet MSL. They are situated ap- proximately 300 feet north of the existing Watana field camp, and 30 feet east of the existing water suppiy and electrical line that runs northward from the camp. The hi-vols are well situated )n a location that will provide a repre- sentative background TSP sample with a minimal chance of sample contam- i nation caused by campsite emissions. slopes upward very gently to the north. The terrain near the samplers As shown by the photographs in Figure 5, the ground cover around the samplers consists of typi ca 1 1 ow tundra vegetation, and the nearest sparse trees are situated approxi- mately 150 feet from the hi-vols. The emission sources at the field camp include a diesel electric generator and a refuse incinerator. Ho~1ever, those emission sources are located approximately 300 feet south of the samplers, and the onsite meteorological data indicate that the summer winds seldom blow from the south. 5389A II-1 ~ ~ !I ~ i(!j ~. ..

The location of this sampler relative to the proposed damsite is shown in Figure 3. The Susitna River hi-vol was requested by ADEC to detennine whether windblown dust eoncentrations near the gravel bars are higher than the dust concentrations in the plateau regions near the campsite. The configuration of the Susitna River hi-vol is shown in Figure 6. The sampler is located at coordinates Alaska State Plane, Zone 4, N 3,226,900 and E 729,500, in a clearing north of the river at elevation 1,435 feet MSL. The diesel generator and its fuel tank are situat~d 76 feet northwest of the hi-vols, in a location that should minimizH the influence of the generator exhaust on the TSP measurements. As shown by the photographs in Fi gt.:re 7, the hi -vo 1 s have exce 11 ent exposure downstream and toward the river, with reason~bly good exposure upstream and away from the river. Although there hav·e been no onsite wind measurements taken at the river level, it is lik~ly that the pre- vailing winds will blow either upriver or downriver along the valley. B. MONITORING EQUIPMENT SPECIFICATIONS 1. Hi-Vol Descriptions The three hi-vols are identical General Metal Works Model 2000 units. All three units are equipped with electromechanical ?-day time switches and elapsed time indicators. The two collocated hi-vols (Units 1 and 2) at the Watana field camp are operated on continuous line power from the main camp generator. Unit 3 at the Susitna River is powered by a 5-kW Lamborghini diesel generator, with a 55-gal fuel tank. 5389A II-5 .. 0 0 z "TI ~ c: JJ )> -f -0 z 0 "TI 11 --'· en t.Q c c -s en C1> -m -1 z )> lJ -< m :a :I: -I < 0 r- Site Location: Generator & Fuel Tank N 3,226,900 E 729,500 Alaska Plane Coord.

L The hi-vols are mounted on sampling platfonns~ as shown in Figure a. The filters on all three hi-vols are situated 8.5 feet above ground level. The hi-vols are finnly bolted to the platforms to avoid the units being blown down by wind gusts. • Spare blower units and spare motor brushes are kept at the field camp. ~· The blowers are inspected prior to the test period, and any faulty blower can be replaced with the spare unit within an hour. The motor brushes on all the units will be replaced at roughly 200-hour operating periods. 2. Flowr·ate Calibration Equipment The hi -vol fl owrates are measured before and after the 24-hr sampling period using a Kurz Model 341 calibration unit. This unit is an elec- tronic, hot-wire anemometer' mass flowmeter that directly indicates the sampler f'lowrate in standard cubic feet per minute (SCFM, 25°C, 1 atiTi); · The electronic flowmeter will be factory calibrated at the midpoint of the sampling program. As an additional spot check to ensure accurate flowrate measurements, the electronic flowmeter will be checke·d onsite on a bi-weekly basis against a standard critical orifice ("top hat 11 ) calibrator. C. SAMPLING SCHEDULE ADEC has specified that the three hi-vols should be run on a 3-day sam- pling frequency. The required sampling dates are shown in Table 2. A 11 three units wi 11 be operated on a 3-day schedule through September 1984. The collocated Units 1 and 2 will be operated from midnight to midnight on the specified sampling days. Unit 3 on the Susitna River is accessible only by helicopter and is powered by a diesel generator, so that unit will be operated from 10:00 am on the designated sampling day to 10:00 am the following day. 5389A II-8 .. r L ) t. ! . l ..

Flowrate Calibration The flowrate for each hi-vol is measured before and after each sampling run, by using a Kurz Model 341 electronic calibratore This unit is a hot-wire anemometer mass flowmeter that reads directly as standard cu- bic feet per minute (scfm), thereby eliminating the need. for ambient temperature and pressure corrections. To ensure accurate flow measure- ments during the program, the Kurz flowmeter wi 11 be checked at the factory d'Aring early August. 2. Analytical Balance The hi-vol filters are weighed on a Mettler electronic analytical bal- ance. The balance is checked by weighing several calibration weights. In accordance with the federal guidelines (EPA 1979}, the balance will be recalibrated by a factory technician if the indicated weight differs from the calibration weight by more than + 0.5 mg. B. INTERNAL QUALITY CONTROL PROCEDURES 1. Sampler Flo~rate Checks A single-point flowrate audit will be perfonned every two weeks to identify any possib'l e i nconsi stenci es in the Kurz electronic flowmeter that is being used for primary fl Oil! measurement. The e 1 ectroni c flow- meter will be checked against a standard critical orifice flowmeter (General Metal Works} at a single flowrate (45-50 scfm). The flowrates measured by the two devices will be recorded in the field on calibra- tion 1 og fonns (Figure 11 ) • The percent fl owrate differences between the two fl owmeters wi 11 be reported by using a standard EPA reporting fonn (Figure 12}. In accordance with the federal guidelines {EPA 1979), the Kurz electronic flowmeter will be recalibrated if the per- cent difference approaches 7 percent. 539PA I I I-1 .. .. .. ;~t:·-"...;:'-· :~··~~ ~ Ambient Barometr·ic Manometer Calculated Electronic Flowrate Remarks Date Temperature Pressure ~H Orifice Flowmeter Deviation T().. ~ (inches Flowrate Os QM (%) oF OK (mmHg) H 0) m~/min ft 3/min ., ft 3/min 2 I :c -'• I < 0 __. ., .., --' ...... ·o tO :E: s::: -j ~ SlJ ro c+ ro __. __. ):::> s::: 0.. ...... c+ ., 0 -s 3 "t.""'- 25 ~~ • ~2§ zu::t] l> ~~ Q D ~[jijil OK = oc + 273 ft 3/min = 35.3 x m3 /min Flow Deviation = <§J 100 X (Qs -Qm)/Qs ~ ~~ mmHg = 25.4 x (in.

TSP Measurement Precision The TSP measurements taken by the collocated Units 1 and 2 will be com- pared for each sampling run, and will be reported by using & standard EPA reporting form (Figure 13). In accordance with the federal guide- lines (EPA 1979), the tests for all 3 units will be considered valid if the measured TSP concentrations at t~~e collocated samplers are within 15 percent of each other. 3. Filter Weight Audit At least 10 percent of the pre-weighed and exposed filters will be re- dessicated and re-weighed, to confirm the precision of the filter weight measu;·ements. The results of the fi 1 ter weight checks wi 11 be recorded on laboratory quality control fonns (Figure 14). In accor- dance with the federal guidelines (EPA 1979), the filter weighings will be considered valid if the initial and re-weights are within~ 5 mg. C. INDEPENDENT AUDITS . An independent audit of all tasks associated with the hi-vol program will be conducted at the midpoint of the program. An air quality spe- cialist from Harza-Ebasco will review the following: o Laboratory procedure:s; o Filter loading and flowrate measurement; o Sample handling. The results of the independent audit will be recorded on a standard "Checklist for Use by Auditor for Hi-Vol Method 11 fonn, which is shown in Figure 15. 5390A III-4 .. • r-····-- ~ I p .

Field Instrumentation The Watana meteorological station 1s checked monthly to verify operability of the sensors. The measurements of the parameters are recorded and reported on stanciaiJized forms. The sensors are checked as follows: The temperature sensor 1S compared to a portable thermometer. The Relative Humidity (RH) sensor 1s checked with a sling psychrometer when the temperature exceeds 0°C. The Wind Speed and Direction sensors are checked by visual observation of wind vane orientation and perceived actual wind speed. The Solar Radiation sensor . 1S the determining checked by solar radiation intensity based on cloud cover, sun angle and atmospheric interference (e.g. dust, water vapor). 5 .. I u I I 1 ~ w ' ' ·taj .... ' i The Long Wave Radiation sensor is checked hy compar1.ng the radiometer signal strength "before" and "after" the amplifiers and also at the recorder connection to verify proper signal transmission. The measured value is inspected for conformance with expected ranges for the g1.ven temperature and sky cover and operability of the conditions. The proper polarity longwave sensor 1.s checked by compar1.ng its reading with and without the observer's hand held over the sensor dome. B. DATA REPORTING TO ALASKA DEC A meteorological monitoring report will be submitted to Alaska DEC prior to preparation of any materials for the Prevention of Significant Deterioration rev1.ew. The meteorological data at the Watana station for the period October 1, 1983 to September 30, 1984 will be used as input to the computer dispersion modeling to predict the worst case 24-hour ~nd annual air quality impacts of the Watana dam construction. The meteorological monitoring report will include the following data for the Watana station: 0 0 67793 841005 Hourly average weather data for each day of the period October 1, 1983 through September 30, 1984, listed by calendar day. The report format will be identical to that shown in Figure C-1 except that data will be listed hourly instead of on a 3-hour basis. Daily average weather data for the period October 1 , 1983 through September 30, 1984 listed by calendar month. will be identical to that shown in Figure C-2. 6 The report fonnat .. ~u ' I LJ u "' v ..... _U ....... _W - i -~ .......; 0 0 0 67793 841005 The annual joint frequency distribution of wind direction and wind speed for the ~eriod October 1, 1983 through September 30, 1984.
