The majority of the data included in this report were submitted to EPA by the states from their ambient monitoring networks in accordance with 40 CFR 58. The only data from industrial monitors which have been included are from EPA-required networks in New Hampshire and from Maine's licensing program which supplements the state network. This report is intended to list potential nonattainment areas for planning purposes. The majority of data used has been evaluated and verified by EPA; however, for the areas listed as nonattainment, the data may require further evaluation by both EPA and the states. Table 1 is a summary of the status of the National Air Monitoring Sites (NAMS) and the State/Local Air Monitoring Sites (SLAMS) submitting data to Region I. This table lists the number of sites operating, the required number of sites, the number of sites reporting precision and accuracy data, and the number of sites not meeting EPA minimum data capture requirements. Table 2 shows the number of stations violating the National Ambient Air Quality Standards (NAAQS) and the total number of stations reporting data during 1987. There were no stations in violation of the SO2 standards. For particulates, three stations were in violation of the 24 hour primary standard, and 20 stations were in violation of the 24 hour secondary standard. The annual primary standard was violated at six stations. Two stations were in violation of the CO 8-hour primary standard, and no stations were in violation of the 1-hour primary standard. For ozone, there were 21 stations in violation of the 1-hour primary standard. No stations violated the NO2 annual primary standard. No stations violated the quarterly mean for lead. Table 3 lists every state site in New England. The information presented compares the measured values to each NAAQS. The information included is the number of exceedences, the maximum and second high values, and the annual means (geometric mean for TSP, arithmetic mean or average for SO2, PM10 and N02) • Those stations reporting a maximum above the standard, but a second high below the standard are included in this table. For intermittent data, an annual mean is not valid unless there are four valid quarters. To be considered valid for TSP, a quarter must have at least five values; and if any one month is missing, each of the other two months must have two or more values. For PM10, 75% of the scheduled samples must be available for a quarter to be validated. For continuous data, 75 percent of the year must be available to calculate a valid annual average. ------- Table 4 shows the number of stations violating the NAAQS by Air Quality Control Region (AQCR), as well as the total number of monitors in each AQCR. A map delineating the AQCRs in Region I is included at the end of this table (Figure 1). Table 5 has been developed to point out areas where air quality levels have exceeded the emergency, warning, or alert episode levels. An air pollution alert (warning or emergency) will be called when specified pollutant concentrations are reached provided that meteorological conditions are such that these levels can be expected to persist for 12 hours or more. In the case of ozone, an alert (warning or emergency) will be called if the situation is likely to recur within the next 24 hours. Episode levels were reached or exceeded for CO at one site. Tables 6 and 7 list the precision and accuracy data submitted by the six New England states. The 95% probability limits for six criteria pollutants are given as a network average for each state. Table 8 lists the results from the Region I audit program for TSP, SO2, CO, NO2, PMio and °3- Tne results presented on a state-bystate basis give the number of satisfactory, marginal, and unsatisfactory audits. Table 9 and 10, respectively, list the nonattainment areas in New England with the last reported violation and the attainment and unclassified areas in which there were recent violations of the NAAQS. Following Table 10 is a discussion of air quality in New England for the criteria pollutants. This discussion includes several charts of selected air quality monitoring sites which show a linear regression for TSP, Pb, CO, CO2, and NO2 during the last five years. For ozone, a chart of the number of days exceeding the standard each year for the last five years is used. ------- NATIONAL AIR QUALITY STANDARDS5 Pollutant Averaging Time Primary Standards*3 Secondary Standards0 502 TSP PM10d CO 03 N°2 Pb Annual Arithmetic Mean 24 hours 3 hours Annual Geometric Mean 24 hours Annual Arithmetic Mean 24 hours 8 hours 1 hour 1 hour Annual Arithmetic Mean Calendar Quarter Arithmetic Mean 80 ug/m3 (0.03 ppm) 365 ug/m3 (0.14 ppm) — 75 ug/m3 260 ug/m3 50 ug/m3 150 ug/m3 9 ppm 35 ppm 0.12 ppm 100 ug/m3 (0.05 ppm) 1.5 ug/m3 1300 ug/m3 (0.5 ppm) 60 ug/m3 150 ug/m3 Same as Primary Standard Same as Primary Standard Same as Primary Standard Same as Primary Standard Same as Primary Standard Same as Primary Standard Same as Primary Standard a National standards other than those based on annual arithmetic means or annual geometric means are not to be exceeded more than once a year. b National Primary Standards: The levels of air quality necessary, with an adequate margin of safety, to protect the public health. c National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant. d PM10 replaced TSP as the ambient particulate standard effective July 31, 1987, and includes only those particles with an aerodynamic diameter of less than or equal to a nominal 10 microns. ------- TABLE 1 1987 SUMMARY OF NEW ENGLAND NAMS/SIAMS CT ME MA NH RI VT TOTALS Number Operating0 36/36 3/3 41/41 3/3 14/14 2/2 66/66 Number NOT meet- ing EPA'S TtriniTtmn data capture. 0 19 SIAMSb 66/66 15/15 16/16 32/32 10/10 11/11 154/154 Number NOT meet- ing EPA's mininun data capture 0 0 2 17 NAMS/SIAMS Percent of required: Precision Data 100 100 100 100 100 100 Accuracy Data 100 100 100 100 100 100 a NAMS - National Air Monitoring Sites b SIAMS - State/Local air Monitoring Sites 0 x/y - x is the number of sites operating y is the total number of sites required to be operated d Adjusted for seasonal monitoring and site start-^ups and terminations ------- TABIE 2 NUMBER OF STATIONS VIOLATING NATIONAL AMBIENT AIR QUALITY STANDARDS SQ2 TSP m CQ Standard Annual Primary 24-hour Primary* 3-hour Secondary* 1 Annual Primary 24-hour Primary* 24-hour Secondary* CT ME MA NH RI VT Annual Primary 24-hour Primary 8-hour Primary* 1-hour Primary* 80 ug/m3 365 ug/m3 1300 ug/m3 75 ug/m3 260 ug/m3 150 ug/m3 50 ug/m3 150 ug/m3 0/20 0/20 0/47 0/47 2/47 1/4 1/4 0/18 0/18 0/50 1/50 13/50 0/13 1/13 0/11 0/11 3/20 1/20 3/20 0/7 0/7 0/14 0/14 1/21 0/21 1/21 0/3 0/3 0/3 0/3 0/3 0/12 0/12 1/12 0/2 0/2 0/3 0/3 0/6 0/6 1/6 0/4 0/4 9 ppm 1/5 0/1 0/8 1/2 0/2 0/1 35 ppm 0/5 0/1 0/8 0/2 0/2 0/1 NQ2 1-hour Primary* Annual Primary 0.12 ppm 9/10 5/10 3/14 1/6 2/2 0/2 100 ug/m3 0/4 0/0 0/6 0/1 0/1 0/1 Quarterly Mean 1.5 ug/m3 0/47 0/5 0/6 0/8 0/5 0/0 *Uhless the second highest average exceeds the NAAQS, there is no violation. x/y - x is the number of stations in violation. y is the total number of stations.

Tables 6 and 7 list the precision and accuracy data submitted by the six New England States. The data listed in these tables are calculated from a known standard and are arithmetic averages of quarterly summary data. The accuracy data in Table 7 are only for the lowest report concentration range. For TSP, the accuracy limits apply only to the flow measurement, and the precision limits are the 95% confidence limits between co-located monitors. From these tables, CO has the lowest probability limits; they are generally within + 10%. All the other pollutants reported are, in general, within approximately + 17%. Although no acceptance criteria have been set by EPA to date, Region I expects this type of performance to be satisfactory. For comparison, the 1986 National Statistics are also included in Tables 6A and 7A. Several States have shown a deterioration in these parameters. This is primarily a result of aging equipment. 36 ------- TABLE 6 1987 PRECISION DATA FOR NEW ENGLAND ANNUAL AVERAGE PROBABILITY LIMITS IN PERCENT CT* ME MA NH RI VT SO2 -09 to +08 -13 to +08 -16 to +08 -12 to +10 -09 to +06 -11 to +04 CO -09 to +07 -03 to +02 -04 to +05 -09 to +06 -04 to +07 -05 to +01 NO2 -10 to +08 -13 to +10 -02 to +11 03 -09 to +07 -09 to +09 -09 to +08 -11 to +01 -04 to +04 TSP -09 to +11 -08 to +12 -15 to +15 -08 to +15 -10 to +13 -06 to +05 Fb ** -12 to +10 -16 to +17 -07 to +06 (analysis) * partial data ** insufficient data TABLE 6A 1986 NATIONAL STATISTICS S02 CO N02 03 TSP Pb -10 to +10 -09 to +09 -11 to +11 -10 to +08 -12 to +13 -20 to +20 37 ------- TABLE 7 1987 ACCURACY DATA FOR NEW ENGLAND ANNUAL AVERAGE PROBABILITY LIMITS FOR THE LOWEST ODNCENIBATION (CONTINUOUS METHODS), FLOW RATE (TSP), AND ANALYSIS (It)) REPORTED IN PERCENT CT* ME NH RI _VT_ SO2 -08 to 408 -08 to +13 -13 to +13 -12 to +11 -08 to +07 CO -10 to +06 -14 to +07 -06 to +10 -10 to +02 -01 to +09 -15 to +09 j^ ** _13 to +14 -22 to +24 03 -08 to +06 -11 to +11 -09 to +03 -05 to +10 -04 to +05 -13 to +09 TSP -06 to +03 -03 to +08 -08 to +05 -07 to +07 -06 to +05 -05 to +04 Pb -07 to +02 -12 to +17 -17 to +15 -11 to +08 * Partial data ** Insufficient data TABLE 7A 1986 NATIONAL STATISTICS S02 CO N02 03 TSP Pb -13 to +12 -08 to +08 -13 to +11 -17 to +16 -08 to +08 -11 to +09 38 ------- REGION I 1987 PERFORMANCE AUDIT PROGRAM Region I conducts an audit program to determine the performance of ambient air monitoring systems and to provide their operators with technical assistance in improving data quality. Continuous air monitors are audited by allowing them to sample gas mixtrues containing known concentrations of specific pollutants and noting the analyzers' responses. High-volume air samplers for TSP, lead and inhalable particulates (PM-10) are audited by attaching a flow reference device and comparing a known air flow rate with the rate recorded or indicated by the sampler. A total of 74 audits were conducted in the six New England states for particulates (TSP, lead, and PM10) , SO2, CO, N02 and ozone by personnel from Region I. In general, the results were very good with 70 audits (95%) satisfactory, 3 audits (4%) marginal, and only 1 audit (1%) unsatisfactory. These results are similar to those achieved in 1986. Particulate sampler audit results were relatively unchanged from 1986, during which 4% of the audits were marginal and 3% were unsatisfactory. In 1987, 5% were marginal, and 3% were unsatisfactory. Sulfur Dioxide and ozone audits were generally good in all six states. Table 8 summarizes the results of the audit program on a state-by-state basis. 39 ------- TABLE 8 REGION 1 PERFORMANCE AUDIT PROGRAM1 - 1987 Particulates2- Number of Audits Number of Satisfactory Audits Number of Marginal Audits Number of Unsatisfactory Audits SQ2 Number of Audits Number of Satisfactory Audits Number of Marginal Audits Number of Unsatisfactory Audits CD Number of Audits Number of Satisfactory Audits Number of Marginal Audits Number of Unsatisfactory Audits NQ2 Number of Audits Number of Satisfactory Audits Number of Marginal Audits Number of Unsatisfactory Audits CT 9 8 1 0 2 2 0 0 0 0 0 0 0 0 0 0 ME MA RI VT 15 14 1 0 0 0 0 0 0 0 0 0 0 0 0 0 16 15 0 1 3 3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 8 8 0 0 3 3 0 0 1 1 0 0 1 1 0 0 Number of Audits Number of Satisfactory Audits Number of Marginal Audits Number of Unsatisfactory Audits 8 7 1 0 0 0 0 0 3 3 0 0 2 2 0 0 2 2 0 0 0 0 0 0 iseven of the reported audits were performed by an EPA contractor (RTI) .

The data for these analyses were collected by the New England States and were submitted to EPA in fulfillment of the Federal monitoring requirements. 1987 CONNECTICUT AMBIENT AIR QUALITY SUMMARY TSP/PM10 The highest annual geometric mean for TSP was measured in Hartford at 63 ug/m3 or 84% of the annual primary NAAQS. Annual geometric means were 76% of the standard in Waterbury, 71% in Norwalk. The maximum second highest daily average was measured in Hartford and was 79% of the primary daily NAAQS. There are four PM10 sites, in Bridgeport, New Haven, Waterbury and West Haven. Only the site in New Haven reported levels above the new PM^Q annual standard. The other sites' values ranged from 61% to 67% of the new standard. Pb There were no violations of the NAAQS reporting in 1987. The highest quarterly average was measured in New Haven at 15% of the NAAQS. Waterbury had the second highest quarterly average at 9% of the standard. In general, lead levels are lower than those reported in 1986, 1985, and 1984. CO There were no exceedences of violations of the 1 hour NAAQS reported in 1987. Hartford reported violations of the 8-hour NAAQS. In total, seven 8-hour violations were reported in 1987. The CO trend plot shows a slight downward trend in mean CO levels over the past five years, in Hartford. S02 No violations or exceedences to the NAAQS were reported in 1987. The maximum SO2 annual averages occurred in New Haven at 50% and 45% of the standard. The highest second high 24-hour average occurred in New Haven at 49% of the NAAQS. The SO2 trend plot shows and increase in mean S02 levels in New Haven over the past five years. NO2 The N©2 sites in Bridgeport, East Hartford and New Haven reported values of 52%, 40% and 56% of the annual standard, respectively. These values are generally in line with those reported in 1986, 1985 and 1984. °3 Every site in Connecticut measured either exceedences or violations of the primary NAAQS, except one site in East Hartford. The highest second high daily maximum reading during 1987 was .174 ppm, which occurred in Stratford. The 03 trend plot shows the five year trend in readings over the NAAQS for the Stratford site. 46 ------- 1987 MAINE AMBIENT AIR QUALITY SUMMARY TSP/PM10 A Primary National Ambient Air Quality Standards (NAAQS) TSP violation and three exceedences were measured in Maine. The violation was in Presque Isle. Secondary TSP standards violations were reported in Bucksport, Winslow, Thomaston, Millinocket, Auburn, Bangor, Madawaska, Oxford County, Presque Isle, Washington County, and Westbrook. Exceedences were reported in Augusta, Berwick, Lincoln and Portland. There were no violations of the annual standard. The annual geometric mean was 71% of the NAAQS in Bangor, and 59% in Presque Isle. The TSP sites with the best air quality were Acadia National Park and Bridgton which both reported levels of 17% of the annual NAAQS. Thirteen sites were operated to measure PM10. Only Presque Isle had a violation of the standard. There was one exceedence measured in Madawaska. Lead There were no violations of the quarterly lead NAAQS. The highest statewide concentration was measured in Portland and was 18% of the standard. Maximum levels, measured in Bangor and Presque Isle, were approximately 8% of the standard. Lead levels generally followed a decreasing trend throughout the State. CO The only CO monitoring site in the State is located in Portland. There were no violations to the Maximum 1-hour standard measured levels were 24% of the national standard. The maximum 8-hour measurement was 63% of the standard. The five year trend in Portland shows a very slight upward trend. SO2 There were no violations or exceedences of the standard in 1987. The highest annual arithmetic mean was in Lewiston, at 29% of the standard. The highest 24-hour average was in Rumford, at 70% of the standard. The five year trend in Lewiston shows a decreasing trend, which is consistant with previous years. NO2 Maine is not required to monitor NO2. 03 Of the ten sites operated in Maine, seven monitors had exceedences or violations of the NAAQS. The highest value recorded (.156 ppm) was measured at the Cape Elizabeth site. The value was 130% of the NAAQS. The site measuring the lowest values is located in Bigelow. This site measured a maximum value of .079 ppm or 66% of the NAAQS. The five year trend of the number of days over the NAAQS shows a consistant pattern for the last five years of 1 to 4 days per year over the standard. 47 ------- 1987 HASSACHUSETTS AMBIENT AIR QUALITY SUMMARY TSP/PM10 The primary annual and the secondary 24-hour TSP NAAQS were violated at only one site in Massachusetts, the City Square site in the Charlestown section of Boston. Two other sites, the Southhampton Street site in Boston and the East Columbus Avenue site in Springfield, reported violations to the secondary 24-hour NAAQS. TSP sites with the highest annual geometric means were located in Boston, measuring 143% and 84% of the NAAQS. The highest second maximum daily TSP values were measured in Boston at 112% of the secondary NAAQS. The lowest TSP levels were measured at a rural background site in Ware with levels at 21% of the primary annual geometric mean, and 23% of the secondary NAAQS. For PM10 there are seven sites operating in Boston, Lawrence, Springfield and Worcester. No sites are in violation of the new standard. Lead Routine monitoring for lead began in 1982 with sites established in Boston, Lowell, Springfield and Worcester. No violations to the quarterly lead NAAQS have been reported from the present network to date. Maximum quarterly lead levels decreased from 1985 and 1986 levels at all sites. The highest site in the State was in Springfield with a maximum quarterly average of 11% of the NAAQS. Maximum quarterly lead levels from other urban areas in the state ranged from 3% to 8% of the NAAQS. CO No exceedences to the 1-hour NAAQS were reported for the seven sites which monitored CO in the State for 1987. One site in Worcester and one in Springfield reported exceedences of the 8-hour standard . The highest second maximum 1-hour average for the State in 1987 was measured at the Central Street Fire Station in Worcester, at 49% of the i-hour NAAQS. The highest second maximum 8-hour average for the State was measured at the East Columbus Ave site in Springfield, at 99% of the NAAQS. SO2 There were no violations of the NAAQS at any of the eleven sites which reported SO2 data for 1987 in Massachusetts. Maximum S02 levels for Massachusetts on an annual basis were reported in Boston at the Kenmore Square site at 55% of the the annual NAAQS. Minimum SO2 levels on an annual basis were measured in Ware at 15% of the NAAQS. Highest second maximum daily SO2 levels were reported for Fall River and Springfield at 38% of the NAAQS. NO2 In 1987, six sites collected NO2 data in Massachusetts. The maximum site in the State was located in Kenmore Square, Boston, where the annual mean was 76% of the NAAQS. 48 ------- °3 As in past years, ozone violations were reported throughout Massachusetts for 1987. Exceedances were recorded at eight out of fourteen sites which operated in 1987. The maximum daily value for 1987 in Massachusetts was recorded in Sudbury at .143 ppm. 49 ------- 1987 NEW HAMPSHIRE AMBIENT AIR QUALITY SUMMARY TSP/PM10 New Hampshire had no violations or exceedences of the primary TSP NAAQS in 1987. There were one violation and two exceedences of the secondary standard. The air quality in Berlin is influenced by manufacturing activity at a local paper mill. The annual geometric means for other areas in New Hampshire were 55% of the standard in Manchester, 53% in Nashua and 76% in Portsmouth. Background levels in Hollis are 39% of the annual standard. Three PM^0 sites were operated in New Hampshire in 1987. Three in Berlin, one in Manchester (with two samplers) , and a new site in Portsmouth. None reported any violations of the standards. Lead There were no lead violations reported in 1987 at the eight sites which monitor this pollutant in New Hampshire. The highest site—a microscale site in Concord—reported a maximum quarterly average which was 6% of the NAAQS. The lowest site in the State, which is located in Hollis, had a maximum quarterly average of 1% of the standard. CO No violations of the 1-hour NAAQS were reported in 1987 ; however, a total of four violations of the 8-hour NAAQS were monitored in Manchester for 1987, compared to nine violations reported for 1986. The maximum 8-hour level was 116% of the standard in 1987. For Manchester, the frequency of violations decreased in 1987 while the magnitude of the violations increased significantly. SO2 No violations of the NAAQS were monitored in 1987. The last violation measured in New Hampshire occured in 1980 at a site in Berlin. N02 Only one site in Manchester collected N02 data in 1987. This site was 40% of the annual aritimetic mean. 03 There were two sites with violations for 03 and another with an exceedence of the 1-hour standard. The highest 1-hour maximum was in Rye Harbor at 150% of the standard. 50 ------- 1987 RHODE ISLAND AMBIENT AIR QUALITY SUMMARY TSP/PM10 For TSP, one violation and two exceedences of the secondary 24-hour NAAQS were reported in 1987; all were measured in Providence. An annual geometric mean equal to the annual secondary standard was reported at the Health Dept. Parking Lot (State Street) site. This value is equivalent to 80% of the primary TSP annual standard. The Sabin St. site, also in Providence, had the highest 24-hour average, at 84% of the primary 24-hour TSP standard. The lowest levels in the state were measured at the University of Rhode Island's Alton Jones campus. At 24% of the primary annual NAAQS and 25% of the 24-hour standard, these background levels are slightly lower than last years.' For PM^o, two sites in Providence and Pawtucket were operated. Both sites reported levels below standards. Lead There were no calendar quarter arithmetic means measured which were greater either than the primary or the secondary NAAQS in 1987. The second highest quarterly average occurred at Westminster Street at 9% of the standard. Pb levels have shown a decrease from 1982 to 1987. CO There were no exceedences of the 1-hour NAAQS in 1987. CO levels measured at the Dorrance Street site in Providence continue to show a downward trend. S02 No violations of NAAQS were reported in Rhode Island over the past six years. The second highest 24-hour value was reported in Providence at 43% of the 24-hour standard. Levels at the Dorrance Street site showed no significant increase over those measured in 1986. N02 The only NO2 site in Rhode Island, located in Providence, reported an annual average which was 50% of the standard. This annual average equaled last year's value. °3 The highest second high daily maximum value reported in Kent County (Alton Jones) was .162 ppm, (130% of the NAAQS) which is the same as the 1986 value of .162 ppm. The highest second high daily maximum value in Providence was .135 ppm or approximately 108% of the NAAQS. Seven days were measured over the standard at the Alton Jones site, while 2 days over the standard were measured at the Rockefeller Library site in Providence. The five year trend illustrated is for the Alton Jones site. 51 ------- 1987 VERMONT AMBIENT AIR QUALITY SUMMARY TSP/PM10 There was one exceedence and one violation of the secondary TSP 24-hour standards (150 ug/m3) observed in Vermont for 1987. The violation occurred at the Rutland site where a value of 183 ug/m3 was recorded. The next highest value at this site was 177 ug/m3. The exceedence occured at the Barre site, where the value was 151 ug/m3. Maximum 24-hour TSP levels for the rest of Vermont were below the NAAQS. The 1987 daily maxima for each of these sites ranged from 138 ug/m3 in Burlington to 65 ug/m3 in Randolph. The annual geometric mean for Barre was 76% of the primary annual NAAQS, while Burlington TSP levels averaged 55% of the standard. Levels at the remaining sites were all less than 53% of the standard with the lowest levels measured at the Randolph site, at 35% of the standard. For PM10, eight sites are being operated. All show attainment. Lead Vermont is not required to and does not operate a monitoring network for lead. CO Carbon monoxide is monitored only in Burlington. Maximum levels at this site were 34% of the 1-hour NAAQS and 73% of the 8- hour standard. These levels were lower than 1986 maxima. The five year trend line for Burlington shows a slight upward trend. S02 The Burlington site is the only site which monitors SO2 year- round in Vermont. Levels at this site for 1987 were 13% of the daily NAAQS and 19% of the annual NAAQS. Monitors in Barre and Rutland operate from September through April each heating season. Maximum levels at these two sites were 19% of the daily standard in Barre and 28% of the daily standard in Rutland. The five year trend line for Burlington shows a slight downward trend. NO2 N02 is monitored at one site in Burlington. The arithmetic mean for 1987 is 38% of the annual NAAQS. °3 No violations of the ozone NAAQS were monitored in Vermont for 1987. The maximum daily values for the year were 0.101 ppm for Bennington and 0.089 ppm for Burlington. Ozone levels have remained relatively stable in Vermont since 1981 and show attainment through 1987. 52 ------- FIVE YEAR TREND CARBON MONOXIDE n 0.5 1983 1984 1985 1986 1987 1988 Legend O HARTFORD.
